Sound Waves and Light Waves

Occur when the disturbance is at a right angle to the direction the wave is moving 

Ex: Heat and light waves

• Transverse wave

• Longitudinal wave

Two sound waves of different frequencies interfere and produce a resulting waveform shown with four points (W, X, Y, and Z) marked on the new wave.

At which point will the sound be the loudest ?

• W

• X

• Y

• Z
