Sound Waves Review

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the sound wave. It determines the loudness of the sound; higher amplitude means a louder sound.

Front

What is frequency in sound waves?

Back

Frequency is the number of waves that pass a point in one second. It determines the pitch of the sound; higher frequency means a higher pitch.

Front

What is wavelength in sound waves?

Back

Wavelength is the distance between two consecutive points of the same phase in a wave, such as from crest to crest. It is inversely related to frequency.

Front

How does sound travel through different mediums?

Back

Sound travels through solids, liquids, and gases, but it travels fastest through solids because the particles are closer together.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves are perceived as higher pitched sounds, while lower frequency waves are heard as lower pitched sounds.

Front

What is the speed of sound in air compared to water?

Back

Sound travels faster in water than in air because water particles are closer together than air particles.

Front

What type of matter does sound travel fastest through?

Back

Sound travels fastest through solids.

Front

What is the order of speed of sound through different mediums from slowest to fastest?

Back

The order is air, water, wood, steel.

Front

Why do sound waves travel faster in solids than in liquids?

Back

Sound waves travel faster in solids because the particles in solids are more closely packed together, allowing the sound to transmit more quickly.

Front

What happens to the pitch of a sound if the frequency decreases?

Back

If the frequency decreases, the pitch of the sound becomes lower.
