Wavetank Lab Illustrations

Parallel wavefronts like these are created by using a flat surface to create waves.

Fron this picture can you determine the wavelentgh, frequency and period of this wave?

Circular wavefronts are created from POINT sources, like a dripping water.

From this picture can you determine the wavelength, frequency and period of these waves?

Can you see the "bending" of the wave? This process is caused by a change in depth of water, or a change in speed due to different depths. This process is called Refraction

This picture shows Reflection of light. It occurs when the wavefront meets a solid object. Notice how the initial wave and reflected waves obey Snell's Law (incedent angle = reflected angle)

Even when you observe circular waves coming into contact with a solid boundary, Snell's Law is observed.
