A ray of light is incident on the surface of a glass plate of refractive index 1.6 at polarzing angle. Calculate the angles of reflection and refraction.

Text Solution

Verified by Experts

Refraction index of glass n=1.6
From Brewster's law we have `n= tan theta_p`
`thereforetheta_p=tan^-1(n)=tan^-1(1.6)=58^@`
i.e., angle of incidence `theta_p=58^@`
`therefore` Angle of reflection =`58^@`
Also, `theta_p+r=90^@`
`r=90^@- theta_p=90-58^@=32^@`
Result: ANgle of reflection =`58^@`
Angle of refraction =`32^@`
