Light and remote sensing

Light travelling from one medium to another medium bend while crossing the interface is called

• Refraction

• Reflection

• Polarization

• Diffraction

(a)   law states that ratio of sine of angle of incidence to sine of angle of refraction constant

The ratio between the angle of incidence and angle of refraction is called (a)  

Formula for refractive index of a glass prism is................

• Sin( A+D)/sin (A/2)
