Sound waves

Front

What is echolocation?

Back

Echolocation is a biological sonar used by several kinds of animals, including bats, to locate objects by emitting sound waves and listening for the echoes that return.

Front

What is a rarefaction in a sound wave?

Back

Rarefaction is the region in a longitudinal wave where the particles are spread apart, resulting in lower pressure.

Front

What factors affect the speed of sound?

Back

The speed of sound depends on the medium through which it travels and the temperature of that medium.

Front

What is frequency in the context of sound waves?

Back

Frequency is the number of wavelengths that pass a point each second, measured in Hertz (Hz).

Front

What happens to amplitude when a sound is louder?

Back

When a sound is louder, the amplitude of the sound wave increases.

Front

Define wavelength in sound waves.

Back

Wavelength is the distance between two consecutive points of the same phase in a wave, such as crest to crest or trough to trough.

Front

What is pitch in relation to sound?

Back

Pitch is the perceived frequency of a sound; higher frequencies correspond to higher pitches.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves produce higher pitches, while lower frequency sound waves produce lower pitches.

Front

What is compression in a sound wave?

Back

Compression is the region in a longitudinal wave where the particles are close together, resulting in higher pressure.

Front

How does temperature affect the speed of sound?

Back

As temperature increases, the speed of sound in a medium also increases due to faster particle movement.
