Wave Equations

Wave Speed (v) = Distance (x) / Time (t)

Wave Speed (v)(m/s) = frequency (f)(Hz) x Wavelength(m)

Multiple Choice

What is the correct equation for calculating Wave Speed

• Distance / Wave Length

• Time / Distance

• Frequency x Wave Length

• Distance x Time

Multiple Choice

Velocity= 600 m/s

Wavelength= 2.0m

Frequency= _________

• 300 hertz

• .0033 hertz

• 3000 hertz

Multiple Choice

Velocity= ________

Wavelength= .5m

Frequency= 150 hertz

• .75 m/s

• 75 m/s

• 300 m/s

Multiple Choice

A wave has frequency of 50 Hz and a wavelength of 10 m. What is the speed of the wave?

• 500 m/s

• 50 m/s

• 5 m/s

• 0.5 m/s

Multiple Choice

What is the speed of a wave with a wavelength of 10m and a frequency of 2 kHz?

• 200m/s

• 20,000 m/s

• 20 m/s

• 0.2 m/s

Transverse

e.g. a water wave, objects will bob up and down and the wave passes.

Longitudinal

e.g tuning fork in air, you don’t get a vacuum by the side of the tuning fork.

Both transfer energy. The wave travels and not the medium.

Multiple Select

Select the transverse waves.

• water waves

• light

• ultrasound

• radio waves

• P waves

Fill in the Blanks

The vibrations in a longitudinal wave are

to the direction of energy transfer.

Fill in the Blanks

In a transverse wave, the vibrations are

to the direction of the wave.

Multiple Choice

Sound waves can travel through a vacuum because they don't require particles.

• True

• False
