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