Front

What is the speed of sound at 40°C?

Back

The speed of sound is fastest at 40°C.

Front

What is a common characteristic of sound waves and light waves?

Back

Both sound waves and light waves transfer energy.

Front

What happens to the pitch of a sound when the source is moving away from the observer?

Back

The pitch of the sound observed by the student is lower.

Front

What is the term for sound with a frequency too low for humans to hear?

Back

Infrasound.

Front

In which type of wave is the particle motion perpendicular to the wave motion?

Back

Transverse wave.

Front

What is the relationship between temperature and the speed of sound?

Back

The speed of sound increases with an increase in temperature.

Front

What is the frequency range of infrasound?

Back

Infrasound refers to sound waves with frequencies below 20 Hz.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, particle motion is parallel to wave motion; in transverse waves, particle motion is perpendicular to wave motion.

Front

How does sound travel through different mediums?

Back

Sound travels fastest in solids, slower in liquids, and slowest in gases.
