Wave Interference and Properties

What is a wave?

• A type of sound that travels through the air.

• A disturbance that moves outward and carries information.

• A solid object that moves up and down.

• A type of light that can be seen.

Which part of a wave is the highest point?

• Trough

• Amplitude

• Wavelength

• Crest

What is the main difference between a transverse wave and a longitudinal wave?

• Transverse waves are faster than longitudinal waves.

• Transverse waves travel through solids, while longitudinal waves travel through liquids.

• In a transverse wave, the movement is up and down, while in a longitudinal wave, the movement is back and forth in the same direction as the wave.

• Longitudinal waves have crests and troughs, but transverse waves do not.

What happens when two waves combine and cancel each other out?

• Constructive interference

• Reflection

• Destructive interference

• Oscillation
