- A Beam Of Radiation Is Propagating Inside A Dielectric Of Refractive Index N 1 5 And Is Incident On A Dielectric Free S 1 (51.72 KiB) Viewed 53 times
A beam of radiation is propagating inside a dielectric of refractive index n= 1.5 and is incident on a dielectric/free space interface. If the angle of incidence is 80° and the radiation has a wavelength of 500 nm in free space, calculate the distance outside the medium at which the electric field amplitude has dropped to 10% of its value at the surface.
