Answer 2

Answer: Option (d) is the correct answer.

Step-by-step explanation:

Electromagnetic spectrum is the spectrum that represents electromagnetic radiations along with their wavelengths and frequencies.

Range of different waves according to the wavelengths are as follows.

Gamma rays : less than 0.01 nm

Radio waves : 1 mm - km

Microwaves : 1 mm - 1 m

X-rays : 0.01 - 10 nm

Infra-red waves : 750 nm - 1 mm

Ultra violet waves : 10 nm 400 nm

Visible range : 390 nm - 750 nm

Thus, we can see that visible regions is a small part of electromagnetic spectrum.

Hence, we can conclude that only a small part of electromagnetic spectrum is visible to us.
