Waves Calculation review

What is the formula to calculate wave speed?

• wave speed = wavelength x frequency

• wave speed = wavelength / frequency

• wave speed = amplitude x frequency

• wave speed = speed of light x frequency

If the frequency of a wave is 20 Hz and its wavelength is 5 m, what is the wave speed?

• 100 m/s

• 50 m/s

• 150 m/s

• 200 m/s

A wave has a frequency of 10 Hz and a wavelength of 2 m. Calculate the wave speed.

• 5 m/s

• 20 m/s

• 15 m/s

• 25 m/s

What are the units for wave speed?

• m/s

• km/h

• cm/s

• miles/h

If a wave has a frequency of 50 Hz and a wavelength of 10 m, what is the wave speed?

• 1000 m/s

• 250 m/s

• 500 m/s

• 75 m/s

Explain the relationship between frequency, wavelength, and wave speed.

• wave speed = frequency - wavelength

• wave speed = frequency + wavelength

• wave speed = frequency / wavelength

• wave speed = frequency x wavelength

Calculate the wave speed if the frequency is 15 Hz and the wavelength is 3 m.

• 45 m/s

• 30 m/s

• 12 m/s

• 20 m/s

How does the frequency of a wave affect its wave speed?

• Wave speed is constant regardless of the frequency of the wave.

• Wave speed is inversely proportional to the frequency of the wave.

• Wave speed is determined by the medium through which the wave is traveling.

• Wave speed is determined by the frequency of the wave.

If the wave speed is 300 m/s and the wavelength is 20 m, what is the frequency of the wave?

• 30 Hz

• 15 Hz

• 25 Hz

• 10 Hz

If the wave speed is 400 m/s and the frequency is 25 Hz, what is the wavelength of the wave?

• 20 m

• 12 m

• 16 m

• 30 m
