What is the wavelength of a wave having a frequency of 2500 Hz

We will assume that the wave is moving in free space, thus, the velocity of the wave would be equal to the speed of light = 3 * 10^8 meters/sec

The velocity of the wave can be calculated using the following rule:

velocity = frequency * wavelength where:

velocity = 3 * 10^8 m/sec

frequency = 2500 Hz

wavelength is the unknown that we want to calculate.

Substitute with the givens in the above equation to get the wavelength as follows:

3 * 10^8 = 2500*wavelength

wavelength = 120 * 10^3 meters

We need to know what type of wave it is
