PROPERTIES OF WAVES

WAVES A Wave is the motion of disturbance. In a wave, particles vibrate with simple harmonic motion. Medium: a physical environment through which a disturbance can travel (Ex: water or air) Mechanical Waves: a wave that requires a medium through which to travel Sound waves can not travel through outer space. Electromagnetic Waves: do not need a medium to travel Ex: visible light, radio waves, ultraviolet, microwaves, Xrays

RELATIONSHIP BETWEEN SHM AND WAVE MOTION Sine Wave: a wave whose source vibrates with SHM. Name given from the graph of the trigonometric function: y=sin x If we focus on one point of the rope, we can see that it vibrates around its equilibrium position with SHM.

MEASURES OF SIMPLE HARMONIC MOTION

TRANSVERSE WAVES Transverse Wave: a wave whose particle vibrate perpendicularly to the direction the wave is traveling.

LONGITUDINAL WAVE Longitudinal Wave: a wave whose particles vibrate parallel to the direction the wave is traveling.

PRACTICE A spring-block oscillator oscillates with a period of 2. 5 seconds. What is its frequency?

PRACTICE A piano string tuned to middle C vibrates with a frequency of 262 Hz. Assuming the speed of sound in air is 343 m/s, find the wavelength of the sound waves produced by the string.
