Things you need to know before we get started...
~ a medium has tiny parts that are able to move around
~ the frequency is when the fully cycle of a wave is repeated; like in a pattern
Transmission-
If the medium doesn't change.. then the speed must stay the same. If the frequency changes, then the wavelength must change as well.
Reflection-
Reflection means changing which way the wave is going. After reflection happens; the speed of wave, frequency, and wavelength stay the same. When the direction of the wave changes.. the angle of incidence is the same as the angle of reflection.
Refraction-
When a wave bends as it passes from one type of medium to a different type of medium, that is called refraction. An example of refraction would be a Tsunami!
Partial Reflection/ Partial Refraction-
Diffraction-
interference-
