Physics: Waves

Wave motion transfers energy without transferring matter in the direction of wave travel. The shape of a wave does not change. Only the size changes.We can show wave motion with a slinky spring.

Speed: the distance a moving object travels in a certain amount of time.

Frequency: Number of waves that pass a fixed point per unit time; also, the number of cycles or vibrations undergone in unit time by a body in periodic motion. Frequency f. Frequency is usually expressed in units called hertz (Hz). One hertz is equal to one cycle per…
