Change in the apparent frequency of a wave as observer and source move toward or away from each other
Lens such that a beam of light passing through it is brought to a point or focus, lens is thicker in the center
A lens that is thinner in the center than at the edges, a lens such that a parallel beam of light passing through it is caused to diverge or spread out
Combination of transverse and longitudinal waves. The wave moves from one medium to another. EXAMPLE: ocean waves
The maximum height of a wave from its rest position;LARGE AMPLITUDE = MORE ENERGY; SMALL AMPLITUDE = LESS ENERGY
The distance between any two crests or compressions next to each other in a wave; SHORTER WAVELENGTH = MORE ENERGY; LONGER WAVELENGTH =LESS ENERGY
This wave travels up and down while the energy travels left and right. ex: water wave, rope wave
