Question

A diode laser emits at a wavelength of 988 nm . In what portion of the electromagnetic spectrum is this radiation found?

Answer 1

Answer: A diode laser which emits at a wavelength of 988 nm is in the infra-red portion of electromagnetic spectrum.

Step-by-step explanation:

Electromagnetic spectrum shows the wavelength or frequency ranges of different electromagnetic radiations. According to this spectrum, the range for infra-red region is from
`700 to 10^(6) nm`.

Therefor, a diode laser which emits at a wavelength of 988 nm is in the infra-red portion of electromagnetic spectrum.
