Sound Waves

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (like air, water, or solids) and is caused by the vibration of particles.

Front

What is frequency in relation to sound?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). It determines the pitch of the sound.

Front

What is wavelength?

Back

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

Front

How does frequency relate to wavelength?

Back

The higher the frequency, the shorter the wavelength.

Front

What unit is used to measure sound volume?

Back

Decibel (dB) is the unit used to measure the volume or intensity of sound.

Front

What is pitch?

Back

Pitch is the perceived frequency of a sound; it determines how high or low a sound seems.

Front

What is an echo?

Back

An echo is the reflection of sound waves off a hard surface, causing the sound to be heard again.

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 amplitude?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium. It relates to the loudness of the sound.

Front

What is a medium in the context of sound?

Back

A medium is the substance through which sound waves travel, such as air, water, or solids.
