substance through which a wave may travel | medium |
type of wave in which the wave travels perpendicular to the medium | transverse wave |
type of wave in which the wave travels parallel to the medium | longitudinal wave |
the distance between the equilibrium position and the highest (or lowest) point of a wave; the height of a wave | amplitude |
the length of one complete cycle of a wave; the distance between the same point on two waves that are next to one another | wavelength |
the number of complete waves that pass through a given point in one second | frequency |
waves hitting an object and bouncing back | reflection |
the bending of waves as they change speeds | refraction |
the bending of waves around an obstacle | diffraction |
waves passing through one another and then continuing to move in the direction they were originally headed | superposition |
waves adding or subtracting | interference |
adding waves | constructive interference |
subtracting waves | destructive interference |
all forms of electromagnetic radiation (light) that travel in waves | electromagnetic spectrum |
light rays strike a rough surface, are reflected in all directions, and produce an unclear image | diffuse reflection |
light rays strike a smooth surface, are reflected in the same direction, and produce a clear image | specular reflection |
change in the observed frequency of a wave due to the motion of the source of a sound wave AND/OR the observer | Doppler Shift |
