Question

Who discovered the formation of ozone from photochemical reactions?

(a) G.M.B Dobson

(b) Sydney Chapman

(c) Carl Sagan

(d) Henri Buisson

The question was posed to me by my college director while I was bunking the class.

Question is taken from Ozone Depletion in chapter Atmosphere & Greenhouse Gases of Environmental Engineering

Answer 1

Right answer is (a) G.M.B Dobson

To explain I would say: Sydney Chapman was the physicist who discovered that stratospheric ozone if formed when the UV rays from the sun splits oxygen molecules, and the nascent oxygen combines with existing molecules to form ozone.
