Wave Calculations

Front

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

Back

Frequency (f) = Velocity (v) / Wavelength (λ)

Front

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

Back

Wave speed (v) = Frequency (f) × Wavelength (λ)

Front

What type of wave is sound?

Back

Sound is a longitudinal wave.

Front

If a wave has a frequency of 300 Hz and a wavelength of 2 m, what is its speed?

Back

Speed = 300 Hz × 2 m = 600 m/s

Front

What is the wavelength of a wave with a frequency of 5 Hz and a speed of 25 m/s?

Back

Wavelength (λ) = Speed (v) / Frequency (f) = 25 m/s / 5 Hz = 5 m

Front

Calculate the speed of a wave with a frequency of 50 Hz and a wavelength of 10 m.

Back

Speed = Frequency × Wavelength = 50 Hz × 10 m = 500 m/s

Front

What is the unit of frequency?

Back

Hertz (Hz)

Front

What is the unit of wavelength?

Back

Meters (m)

Front

What is the unit of wave speed?

Back

Meters per second (m/s)

Front

If the speed of a wave is 75 m/s and its wavelength is 0.5 m, what is its frequency?

Back

Frequency (f) = Speed (v) / Wavelength (λ) = 75 m/s / 0.5 m = 150 Hz
