Front

What is a transverse wave?

Back

A type of wave where the particle displacement is perpendicular to the direction of wave propagation, such as light waves.

Front

What is a compressional wave?

Back

A type of wave where the particle displacement is parallel to the direction of wave propagation, such as sound waves.

Front

What is a mechanical wave?

Back

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

Front

What is the relationship between amplitude and sound loudness?

Back

Increasing the amplitude of a sound wave makes the sound louder.

Front

What is frequency in the context of waves?

Back

The number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is wavelength?

Back

The distance between two consecutive points in phase on a wave, such as crest to crest.

Front

What is constructive interference?

Back

When two waves meet and combine to form a wave with a larger amplitude.

Front

What is destructive interference?

Back

When two waves meet and combine to form a wave with a smaller amplitude.

Front

Can waves transfer energy through empty space?

Back

Yes, waves can transfer energy through empty space, as seen in electromagnetic waves.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.
