Label the parts of a transverse wave: crest, trough, wavelength, and amplitude.

Crest: Highest point of wave, Trough: Lowest point of wave, Wavelength: Distance between two crests (or troughs), Amplitude: Height from equilibrium to crest (or trough).

Label the parts of a longitudinal wave: compression, rarefaction, and wavelength.

Compression: Region of high density, Rarefaction: Region of low density, Wavelength: Distance between two compressions (or rarefactions).

What is a wave?

A travelling disturbance that transfers energy and momentum.

What is amplitude?

The maximum displacement of a wave from its equilibrium value.

Define wavelength.

The distance from one repeated unit of a wave to the next.

What is the period of a wave?

The time it takes for one complete cycle of a wave to occur.

Define frequency.

The number of cycles of a wave in a given amount of time.

What is a transverse wave?

A wave where the particles vibrate perpendicular to the direction of wave motion.

What is a longitudinal wave?

A wave where the particles vibrate parallel to the direction of wave motion.

Compare and contrast transverse and longitudinal waves.

Transverse: Particles oscillate perpendicular to wave direction; examples include light waves. Longitudinal: Particles oscillate parallel to wave direction; examples include sound waves. Both transfer energy.

Compare the relationship between amplitude and energy in waves.

Higher amplitude: Carries more energy. Lower amplitude: Carries less energy.
