At what angle of incidence should a light ray strike a glass plate of refractive index 1.5 so that the reflected light is completely polarized?

C. 56.3^ — According to Brewsters law, the angle of polarization is given by tan(i) = mu. For mu = 1.5, i = arctan(1.5), which is approximately 56.3 degrees.

$At what angle of incidence should a light ray strike a glass plate of refractive index so that the reflected light is completely polarized?$

A. $3 0^{\circ}$
B. $4 5^{\circ}$
C. $56. 3^{\circ}$
D. $6 0^{\circ}$

Show correct answer & step-by-step solution

Correct answer: C — $56. 3^{\circ}$

Solution

According to Brewsters law, the angle of polarization is given by tan (i_{p}) = μ . For μ = 1.5, i_{p} = arctan (1.5) \approx 56. 3^{\circ} .
