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 refraction
None of these
Fresnel reflection
Snell's law

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);

Neither (A) nor (B)
Both (A) and (B)
The angle of refraction (θr) is given by sin θ₂ = (n₁/n₂) sin θi
The angle of incidence is equal to the angle of refraction
