Question

A certain electromagnetic wave has a wavelength of$625nm$. What region of the electromagnetic spectrum is it found?

Answer 1

1. Given: The wavelength of electromagnetic radiation$=625nm$
2. Analysis:
   1. In an electromagnetic spectrum, the region$400nmto700nm$ belongs to the visible region.
   2. As the given wavelength is$625nm$ and is in the above range.

Hence, wavelength$625nm$ belongs to the visible range.
