Question

An electromagnetic wave in a vacuum has a wavelength of 0.06 M what is its frequency?​

Answer 1

Frequency of the electromagnetic waves is given as

`f = 5 * 10^9 Hz`

Step-by-step explanation:

As we know that the electromagnetic waves can travel with the speed of light in vacuum or in air

So here we know that speed of electromagnetic waves as

`v = 3 * 10^8 m/s`

Now we know the wavelength of the electromagnetic waves as

`\lambda = 0.06 m`

so the frequency of the wave is given by the formula

`f = (v)/(\lambda)`

so we have

`f = (3 * 10^8)/(0.06)`

`f = 5 * 10^9 Hz`
