JEE Main 2022 Physics question
A plane electromagnetic waves travels in a medium of relative permeability 1.61 and relative permittivity 6.44. If magnitude of magnetic intensity is at a point, what will be the approximate magnitude of electric field intensity at that point? (Given : Permeability of free space , speed of light in vacuum )
