Ripple Tank: Single and Double Slit Diffraction and Interference
 
03:06
A ripple tank is placed above a mirror and a projection screen. A horizontal bar, whose frequency can be varied, taps the surface of the water and produces plane waves. The waves are incident on a barrier containing an adjustable opening. With a narrow single slit opening we see a plane wave emerge as a spherical wave on the other side of the barrier. This can be explained by the Huygens-Fresnel principle which states that each point in the slit forms its own spherical wavefront source. With a wider slit, more point sources arise, causing interference patterns due to the larger angles involved with a broader spatial distribution of these sources.

Clapotis Wave Action

Clapotis is a term kayakers use for reflected waves combining with the incoming waves in predictable patterns causing an area of disturbed water where wave heights can explosively spike. - http://www.walter-fendt.de/ph14e/stwaverefl.htm -

Waves and particles
 
03:40
Ripple Tank Applet v1.7f I determined the position of particles against to plane waves from one side and two opposite sides while they are separated and together. My aim was to observe the difference at reflected waves from particle. In my opinion, although the mass composed from sub particles which each one has some frequencies, when they are gathered, their total reflected wave frequency is differentiated. Because the incoming waves regard all particles as a single system, also.

The Original Double Slit Experiment
 
07:40
Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles? The experiment was conducted by Thomas Young and is known as Young's Double Slit Experiment. This famous experiment is actually a simplification of a series of experiments on light conducted by Young. In a completely darkened room, Young allowed a thin beam of sunlight to pass through an aperture on his window and onto two narrow, closely spaced openings (the double slit). This sunlight then cast a shadow onto the wall behind the apparatus. Young found that the light diffracted as it passed through the slits, and then interfered with itself, created a series of light and dark spots. Since the sunlight consists of all colours of the rainbow, these colours were also visible in the projected spots. Young concluded that light consist of waves and not particles since only waves were known to diffract and interfere in exactly the manner that light did in his experiment. The way I have always seen this experiment performed is with a laser and a manufactured double slit but since the experiment was conducted in 1801 I have always thought that it should be possible to recreate the experiment using sunlight and household materials. That is basically what I did here. I will show the interference pattern I observed with my homemade double slit on 2Veritasium but I chose to use a manufactured double slit here to ensure that the pattern was impressive for observers at the beach. Special thanks to Henry, Brady, and Rupert for their cameos, Glen for filming and Josh for helping create the apparatus. Thanks also to the Royal Society for allowing us to view the original manuscript of Young's lecture and the University of Sydney for lending the double slits.

Interference of waves on the surface of water HD
 
00:27
Let us consider two small balls, which oscillate on the water surface. Every ball excites the wave, which interferes with the wave from the other ball. As a result we see on the water surface a typical interference pattern. http://physics-animations.com/

Waves on the surface of water HD
 
00:58
The waves on the surface of the water are neither longitudinal nor transverse. We can see in animation that red ball, which simulates the molecule of the water surface, moves in a circle path. So, the wave on the water surface is the superposition of transverse and longitudinal motions of the molecules. The molecules on the water surface move under the action of surface tension and gravity. Next animation simulates the wave motion of the molecules in the surface layer of water (or other liquid). If the amplitude of this wave is small, then every molecule moves in a circle path. The radii of these circles are diminishing with depth, so the balls in bottom part of animation are still.

All waves can transfer energy from one place to another without transferring any matter. This is done by a series of disturbances or vibrations that carry the energy. Just like the people in their seats, only moving up and down when it’s their turn. Waves can transfer energy through solids, liquids, gases and empty spaces – otherwise known as vacuums. There are two types of waves – which we will look at in more detail in another video, but the basic features are the same. The frequency of a wave is the number of complete waves passing a fixed point in a given amount of time. This time period is usually one second. Frequency is given the symbol f and is measured in units called Hertz. Hertz measure how many complete cycles per second; so how many people in our Mexican wave stand up every second. The frequency and period are often confused. The frequency refers to how often something happens, whereas the period refers to the time it takes to happen. The period of a wave is the time for one complete cycle. So the time taken for one person to stand up, wave and sit down. This would be measured in seconds. When something happens repeatedly we say that the event is periodic and refer to the time for the event to repeat itself. The period of the earth to orbit the sun is 365 days, the period of a day is 24 hours, the period of a typical class at school is 45 minutes. Now for the wavelength… the wavelength is the distance between a point on one wave and the same point on the next wave, for example two peaks or two troughs. Wavelength is given the symbol Lambda from the Greek letter, and is usually measured in metres. Wavelengths can vary hugely in size, x-rays are very short, visible light is here and FM radiowaves are much longer. So we’ve looked at the frequency, period and wavelength so far. Let’s finish with amplitude. As waves travel, they create disturbance. The amplitude of a wave is the distance from the maximum disturbance to its undisturbed position. Think of a very flat sea… and then an incoming wave. The amplitude is the height of the top of the wave from the flat sea. In another video we’ll be looking at the wave speed equation, and connecting wavelengths and frequencies: Wave Equation For now you just need to know what these 4 keys words mean. Frequency, period, wavelength, amplitude SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

Diffraction from a Single Slit (FDTD Animation) (Young's Slit)
 
00:15
The single slit diffraction is illustrated via the use of finite-difference time-domain (FDTD) simulation in which slits with various widths are illuminated by electromagnetic plane waves at a single frequency. When the impinging plane waves reach the slits, they are diffracted into a series of circular waves and the emerging wavefront from the slits become cylindrical waves. Diffraction is basically the phenomenon involving the bending of waves around obstacles and the spreading out of the waves past small openings. Huygen's Principle states that every point on a wavefront acts as a source of tiny wavelets moving forward with the same speed as the wave and the wavefront is the surface tangent to these wavelets.

We learn through Web 2 online collaborative means to develop simulations together with reputable physicists through the open source digital library. By examining the open source codes of the simulation through the Easy Java Simulation (EJS) toolkit, we are able make sense of the physics from the computational models created by practicing physicists. We will share newer (2010-present) simulations that we have remixed from existing library of simulations models into suitable learning environments for inquiry of physics. We hope other teachers would find these simulations useful and remix them that suit their own context and contribute back to benefit all humankind, becoming citizens for the world Abstract Footnotes: website prior to the meeting http://www.phy.ntnu.edu.tw/ntnujava/index.php?board=28.0 Extension of Wee, L.
