Diffraction of light is the easiest to recognize, since it takes only a glance. Looking at something beneath the surface of the water is one example. In spear fishing, the fish appears to be somewhere it is not due to how the water affects light. Water droplets also diffract light in the same way. The diffraction of sound is more difficult to pinpoint, but is most noticeable when solid items, such as walls or columns, are between the listener and the source of the sound. Sound also diffracts when it passes through water in a similar fashion to light. The waves slow down when passing through water, distorting the end result. Dispersion: Dispersion of water waves generally refers to frequency dispersion, which means that waves of different wavelengths travel at different phase speeds. Water waves, in this context, are waves propagating on the water surface, and forced by gravity and surface tension. As a result, water with a free surface is generally considered to be a dispersive medium. Interference:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
