JEE Main 2022 — Electromagnetic Waves Question with Solution
From: JEE Main 2022 (Online) 24th June Morning Shift
Question
A plane electromagnetic wave travels in a medium of relative permeability 1.61 and relative permittivity 6.44. If magnitude of magnetic intensity is 4.5 102 Am1 at a point, what will be the approximate magnitude of electric field intensity at that point?
(Given : Permeability of free space 0 = 4 107 NA2, speed of light in vacuum c = 3 108 ms1)
