Intro to Waves & Wave Calculations

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What happens to the wavelength when the frequency of a wave increases?

Back

The wavelength decreases.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as crests or troughs, move from their rest position.

Front

How do you calculate the frequency of a wave?

Back

Frequency (f) can be calculated using the formula: f = velocity (v) / wavelength (λ).

Front

If a wave has a wavelength of 3 m and is traveling at 60 m/s, what is its frequency?

Back

20 Hz.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed (v) is equal to the product of frequency (f) and wavelength (λ): v = f × λ.

Front

What is the unit of frequency?

Back

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

Front

What is the definition of a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is the definition of a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

If a wave has a frequency of 20 Hz and a wavelength of 2.5 m, how fast is it traveling?

Back

50 m/s.
