Are progressive water waves or stationary water waves produced in a ripple tank?
Both types can be produced depending upon the way that the waves are created; their height and their frequency.
What do the dark and bright fringes on screen of ripple tank represent?
In a ripple tank experiment, the dark and bright fringes on the screen correspond to the interference patterns created by the superposition of water waves. When a ripple tank is set up with a coherent source of waves, such as a vibrating paddle, it generates a series of circular waves that propagate outward. These waves can interact and interfere with each other, leading to the formation of dark and bright fringes on the screen. The dark fringes, also known as nodal lines or nodes, occur where the crest of one wave coincides with the trough of another wave. At these points, the waves destructively interfere, resulting in a minimum amplitude or no displacement of the water surface. Consequently, the water appears darker at these locations. On the other hand, the bright fringes, also called antinodal lines or antinodes, are formed when the crests of the waves align or when the troughs align. At these points, the waves constructively interfere, causing the amplitude of the resulting wave to be higher. The water surface exhibits maximum displacement, and as a result, these areas appear brighter compared to the surrounding regions. The dark and bright fringes in a ripple tank experiment demonstrate the wave nature of water waves and illustrate how the interference of waves can create patterns of varying amplitudes and intensities. These patterns are analogous to the interference patterns observed in other wave phenomena, such as light waves.

How do you make waves in a tank of water that will produce a steady amount of waves?
A little wave generator (a ripple tank) can be purchased or fabricated based on a small battery-powered electric motor. Or, you might use an applet to run a computer generated experiment! Links are provided. Have some fun.
What are some common examples of refraction?
Refraction is the bending (changing direction) of light (or other wave) as it passes from one medium to another. Waves also change speed when refraction occurs. Most of the examples of refraction that people encounter in daily life involve light and either glass or water, but all waves exhibit refraction, including sound and water. 1. A relatively pure example of refraction can be observed if one places a straight object like a pencil partly in a glass of water and then observes the apparent change in the direction of the image of the straight object when it crosses the surface of the water. 2. A prism is an example of refraction. It also illustrates that the extent of refraction of light depends on the color. In a prism, light is refracted as it enters and as it leaves the prism and the light waves of different colors change directions by different amounts so that when they exit the colors are seen at different angles. 3. Rainbows have color because of refraction in a manner similar to a prism. The rainbow results when light waves encounter drops of water. There is also reflection involved and a full explanation is more complicated than the case of a prism. 4. All lenses (including the lenses in eye glasses) function because of refraction. Light enters the lens on one side and because the surface of the lens is curved, the angle of light inside is different depending on the place on the lens surface where it entered. That is called focusing light. It happens again as the light exist the lens. The eye itself has a lens that operates because of refraction and creates the image on the retina of the eye. 5. When you look into water, the objects that you see are not in the location where the image appears. Native peoples who hunted fish with a spear learned that you do not through the spear at the image of the fish because the angle of the light changes coming out of the surface of the water and makes it appear as though the fish is slightly displaced. 6. Sound refracts as does any other wave. One can not easily notice this, but if you are under water and sound enters from the air, the apparent direction will shift by some angle. 7. Water waves refract and it is easily demonstrated with a co-called ripple tank. When the depth of water changes, so does the speed of a wave. In a ripple tank one can place a flat surface on the flat bottom of a tank so there are two different water depths separated by a straight edge. Waves creates in one depth that encounter the edge at an angle will be seen to change direction. This is most obvious for very shallow depths around a centimeter. 8. Ocean waves change speed and so also demonstrate refraction but it is not clearly seen unless there is an edge such as described for the ripple tank. Ocean waves are a different sort of wave than a ripple but still can show diffraction. One can obviously see the change in speed and wavelength of waves as they come to a shore and that is related to the refraction process. 9. In old glass windows the glass is sometimes not very flat and ripples in the glass are evident. (Ripples in water give the same effect.) When you view an image through rippled glass the image is distorted because that light that entered was bent when it came in at an angle different than it was bent on the way out. The bending is refraction and the same kind of refraction as with a lens, but the ripples are irregular where as a lens is carefully smoothed.

A dipper in a ripple tank is bobbing up and down 16 times every two seconds The wavelength of the waves is 2cm how far will it travel in 10 seconds?
The velocity is equal to the frequency times the wavelength. Freq = 8Hz ("per second") wavelength = 2 cm 2x8=16cm/s Then multiply the velocity by the elapsed time... 16cm/s x 10sec. (seconds cancel as units) 160cm
Who invented ripple tank?
Thomas Youngâ??s interest in wave behavior led him also to invent the ripple tank. This tank is still used today to analyze and illustrate wave behavior.
