What is the definition of amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

How does the amplitude of a wave affect its sound?

Back

A larger amplitude results in a louder sound, while a smaller amplitude produces a quieter sound.

Front

What is the relationship between frequency and pitch in sound waves?

Back

Higher frequency corresponds to a higher pitch, while lower frequency corresponds to a lower pitch.

Front

What is a medium in the context of sound waves?

Back

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

Front

Why can't sound travel in a vacuum?

Back

Sound requires a medium to propagate; in a vacuum, there are no particles to transmit the sound waves.

Front

What is the formula for calculating the speed of a wave?

Back

The speed of a wave (v) is calculated using the formula v = frequency (f) × wavelength (λ).

Front

What is wavelength in the context of waves?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

How does the wavelength of a sound wave affect its pitch?

Back

Shorter wavelengths correspond to higher pitches, while longer wavelengths correspond to lower pitches.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have oscillations perpendicular to the direction of wave travel, while longitudinal waves have oscillations parallel to the direction of wave travel.

Front

What is the significance of the wave's crest and trough?

Back

The crest is the highest point of a wave, while the trough is the lowest point; they are important for determining amplitude and wavelength.
