Question

A light wave has a frequency of 12 Hz. Calculate it’s wavelength.

Answer 1

`\lambda=25* 10^6\ m`

Step-by-step explanation:

Given that,

The frequency of the light wave, f = 12 Hz

We need to its wavelength. The wavelength of the wave can be calculated as follows :

`\lambda=(c)/(f)\\\\\lambda=(3* 10^8)/(12)\\\\\lambda=25* 10^6\ m`

So, the wavelength of the light wave is equal to
`25* 10^6\ m`.
