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) by vibrating particles.

Front

What determines the pitch of a sound?

Back

The pitch of a sound is determined by its frequency; higher frequencies produce higher pitches, while lower frequencies produce lower pitches.

Front

What is amplitude in sound waves?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

What is interference in sound waves?

Back

Interference occurs when two or more sound waves overlap, resulting in a new wave pattern that can be constructive (louder) or destructive (quieter).

Front

How does sound travel through different mediums?

Back

Sound travels fastest in solids, slower in liquids, and slowest in gases due to the density and elasticity of the medium.

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

Longitudinal waves have particle movement parallel to wave direction (like sound), while transverse waves have particle movement perpendicular to wave direction (like light waves).

Front

What is a decibel?

Back

A decibel (dB) is a unit used to measure the intensity of sound; it quantifies sound levels relative to a reference level.

Front

What is resonance?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to an external force, amplifying the sound.
