Sound waves, wave interference and wave properties

Front

What is the definition of amplitude in sound waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, which relates to the loudness of the sound.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement of the wave above its rest position.

Front

How is wavelength related to frequency?

Back

A short wavelength corresponds to a high frequency, and a long wavelength corresponds to a low frequency.

Front

What is the formula to calculate the speed of a wave?

Back

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

Front

If a wave has a frequency of 30 Hz and a wavelength of 0.6 m, what is its speed?

Back

The speed of the wave is 18 m/s.

Front

What is wave interference?

Back

Wave interference is the phenomenon that occurs when two or more waves overlap and combine to form a new wave pattern.

Front

What are the two types of wave interference?

Back

The two types of wave interference are constructive interference (waves add together) and destructive interference (waves cancel each other out).

Front

What is the relationship between frequency and pitch in sound?

Back

Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches.

Front

What is the definition of wavelength in the context of sound waves?

Back

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

Front

What is the unit of measurement for frequency?

Back

The unit of measurement for frequency is Hertz (Hz), which represents cycles per second.
