Elements Of Remote Sensing "An Electromagnetic wave falls on to a boundary between two losses less homogeneous media with different refractive indices, a part of the wave is reflected back to the incident medium and the rest is transmitted on to the second media". This phenomenon is known as: Fresnel reflection None of these Snell's law Fresnel refraction Fresnel reflection None of these Snell's law Fresnel refraction ANSWER DOWNLOAD EXAMIANS APP
