Question

On the electromagnetic spectrum, which represents the lowest and highest frequencies?

ultraviolet rays and radio waves

gamma rays and radio waves

ultraviolet rays and gamma rays

radio waves and gamma rays

Answer 1

radio waves and gamma rays    thanks :)

Answer 2

Explanation :

The electromagnetic spectrum describes the different types of waves. The spectrum is arranged in order of increasing wavelength or decreasing frequency.

We know that there is an inverse relation between the frequency and the wavelength i.e.

`f\propto(1)/(\lambda)`

The frequency of the gamma rays is
`10^(19)\ Hz` and the frequency of the radio waves is
`300\ GHz`.

So, the correct option is (b) " gamma rays have lowest frequency and radio waves have highest frequency".
