Wave Calculations Flashcard

Front

What is the formula for calculating wave speed?

Back

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

Front

If a wave has a speed of 250 m/s and a frequency of 500 Hz, what is its wavelength?

Back

Wavelength = Speed / Frequency = 250 m/s / 500 Hz = 0.5 m

Front

A wave has a frequency of 50 Hz and a wavelength of 3 meters. Calculate the speed of the wave using the formula v = f λ.

Back

Speed = Frequency × Wavelength = 50 Hz × 3 m = 150 m/s

Front

What is the relationship between frequency and period of a wave?

Back

Frequency (f) = 1 / Period (T) and Period (T) = 1 / Frequency (f)

Front

A wave's period is 0.2 seconds. What is its frequency?

Back

Frequency = 1 / Period = 1 / 0.2 s = 5 Hz

Front

What is wavelength in terms of wave speed and frequency?

Back

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

Front

If a wave travels at 360 m/s and has a frequency of 120 Hz, what is its wavelength?

Back

Wavelength = Speed / Frequency = 360 m/s / 120 Hz = 3 m

Front

What is the unit of frequency?

Back

Hertz (Hz), which is equivalent to cycles per second.

Front

How do you convert frequency to period?

Back

Period (T) = 1 / Frequency (f) in seconds.

Front

What is the speed of a wave with a frequency of 200 Hz and a wavelength of 1.5 m?

Back

Speed = Frequency × Wavelength = 200 Hz × 1.5 m = 300 m/s
