5000 m/s

Heat from the explosion burns the eardrum.

The explosion triggers smaller explosions inside the ear.

Transverse waves from the explosion cause vibrations that damage the ear.

Compression waves from the explosion cause vibrations that damage the ear.

The particles always move side to side

The particles always move up and down

The particles always move in the same direction as the wave

The particles always move perpendicular to the direction of the wave

It blocks out unwanted sounds.

It converts vibrations into electrical signals

It helps detemine if a sound is in front of or behind you

It reflects high and low frequencies back to their source

Wavelength

The wavelength is not directly affected by the frequency of a wave.

The wavelength decreases.

The wavelength increases.

More specific information is needed to form a conclusion about the wavelength.

Light travels with or without a medium.

Sound must have a medium to travel through.

Both light and sound must have a medium to travel through.

Light travels faster than sound.
