Question

A wave with a frequency of 30 Hz has a wavelength of 40.5 m. How fast is the wave traveling?

Answer 1

Speed of wave = 1,215 m/s

Step-by-step explanation:

Given:

Frequency of wave = 30 Hz

Wavelength = 40.5 m

Find:

Speed of wave = ?

Computation:

⇔ Speed of wave = Frequency of wave × Wavelength

⇔ Speed of wave = 30 Hz × 40.5 m

⇔ Speed of wave = 1,215 m/s

Therefore, speed of wave is 1,215 meter per second.
