Question

Which of the following follows Chapman’s law of variation?

(a) D layer

(b) F1 layer

(c) F2 layer

(d) Both F1 and F2 layer

This question was addressed to me in quiz.

My enquiry is from Radio Wave Propagation topic in division Radio Wave Propagation of Antennas

Answer 1

The correct answer is (b) F1 layer

The best I can explain: Only F1 layer follows the Chapman’s law of variation where F1 region behaves like an E-region. F1 layer is formed by the ionization of O2 atoms. F2 layer does not follow Chapman’s law of variation.
