A wave has a Wavelength of 3 meters and a Frequency of 15Hz. What is its velocity?

Velocity of the wave is 45 m/s

Explanation:

Wavelength of light is given to be 3 m. It measures the distance between two successive crests or troughs of the wave. Frequency is 15 Hz.

Frequency is given by the following equation

f = v/λ, where f is the frequency, v is the velocity of wave and λ is the wavelength.

v = f * λ

⇒ v = 15 * 3 = 45 m/s
