Question

What is the case of reflection, in course of second medium being a perfect dielectric?

(a) Loss of energy during absorption

(b) Total energy reflected back to first medium

(c) No loss of energy in absorption

(d) Total energy transmitted into second medium

The question was asked in semester exam.

Asked question is from Reflection in portion Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Correct option is (c) No loss of energy in absorption

Easy explanation: If the plane wave is incident on a perfect dielectric, part of the energy is transmitted into the second medium and part of the energy is reflected back into the first medium. There is no loss of energy in absorption.
