velocity --------------- frequency times wavelength (1) this is the velocity of the wave

force -------------------- Push or Pull

transverse ------------- Wave on a rope

concave----------------- Type of lens that always provide a diminished image

particle -------------------- Model of light supported by photoelectric effect. (light can behave like waves or particles)

convex---------------------- Diverging mirror.

longitudinal--------------- Sound wave.

wave -------------------------- Model of light supported by interference
