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 Fresnel refraction Snell's law None of these Fresnel reflection Fresnel refraction Snell's law None of these ANSWER DOWNLOAD EXAMIANS APP
