• A. 100-390 nm
• B. 300-390 nm
• C. 100-200 nm
• D. 200-390 nm

Answer 1

The correct option is A 100-390 nm

Visible light - It is that portion of solar radiation which our eyes can see. It consists of radiations having a wavelength between 380 nm to 760 nm.

Ultraviolet radiations-It consists of radiations having a wavelength between 10 nm to 390nm.
