_____ measures the amount of time it takes a wave to pass a fixed point.

• Salinity

• Frequency

• Temperature

• Period

A wave has a frequency of 5 hz and a wave length of 5 m. What is the wave speed (velocity)?

• 25 m/s

• 1 m/s

• 10 m/s

• 0 m/s

A wave has a frequency of 6 hz and a wave length of 5 m. What is the wave speed (velocity)?

• 25 m/s

• 1 m/s

• 30 m/s

• 12 m/s

You can calculate the speed of a wave by using the formula below.

𝑣=𝑓λ

In other words, wave speed or velocity (𝑣) is equal to frequency (𝑓) multiplied by wavelength (λ).

The unit for wave speed velocity (𝑣) is meters/second (m/s), the unit for frequency (𝑓) is hertz (hz) and the unit for wavelength (λ) is meters (m).
