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
Elements Of Remote Sensing According to the Snell's law if an electromagnetic wave is incident in a medium (refractive index n₁) on another medium (refractive index m₂); The angle of refraction (θr) is given by sin θ₂ = (n₁/n₂) sin θi Both (A) and (B) Neither (A) nor (B) The angle of incidence is equal to the angle of refraction The angle of refraction (θr) is given by sin θ₂ = (n₁/n₂) sin θi Both (A) and (B) Neither (A) nor (B) The angle of incidence is equal to the angle of refraction ANSWER DOWNLOAD EXAMIANS APP
