What is the definition of amplitude in a sound wave?

Back

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

What does frequency refer to in sound waves?

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.

What is wavelength in the context of sound waves?

Back

Wavelength is the distance between successive crests (or troughs) of a wave. It is inversely related to frequency.

What is the peak of a sound wave?

Back

The peak is the highest point of a wave, representing the maximum displacement of the wave from its rest position.

What is the valley of a sound wave?

Back

The valley is the lowest point of a wave, representing the minimum displacement of the wave from its rest position.

How does sound travel through air?

Back

Sound travels through air as a series of compressions and rarefactions created by vibrating objects, such as speakers.

What is the relationship between amplitude and loudness?

Back

Higher amplitude means louder sound, while lower amplitude means quieter sound.

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What happens to sound waves when they encounter a barrier?

Back

Sound waves can reflect, refract, or be absorbed when they encounter a barrier, affecting how we perceive the sound.
