Question

The ozone layer absorbs what range of wavelengths of the sun’s radiation?

(a) 0.80 nm – 1.50 nm

(b) 200 nm – 315 nm

(c) 450 nm – 570 nm

(d) 600 nm – 750 nm

I have been asked this question in an international level competition.

This question is from Ozone Depletion in section Atmosphere & Greenhouse Gases of Environmental Engineering

Answer 1

Right answer is (b) 200 nm – 315 nm

To explain: The ozone layer absorbs the medium frequency UV radiations from the sun and hence protects the life forms at the surface from harm.
