Waves/Sound Waves Review

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What does the frequency of a wave affect?

Back

The frequency of a wave affects its wavelength; as frequency increases, wavelength decreases.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

What type of wave is sound?

Back

Sound is a longitudinal wave.

Front

What is the relationship between frequency and amplitude?

Back

Frequency and amplitude are independent properties; changing one does not directly affect the other.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What happens to sound waves as they travel through different mediums?

Back

Sound waves travel faster in solids than in liquids, and faster in liquids than in gases.
