Explanation Given info: The critical angle of total internal reflection is θ c , Let θ p be the polarizing angle n 2 be the refractive index of the transparent medium and n 1 be the refractive index of the air. Formula to calculate the polarizing angle is, n 2 n 1 = tan θ p (1) First calculate the refractive index of medium, formula to calculate the refractive index of sapphire is, n 2 sin θ c = n 1 sin r (2) Here, θ c is the critical angle r is the angle of refraction. Substitute 90.0 ° for r in equation (2) n 2 sin θ c = n a i r sin r n 2 sin θ c = 1 sin 90.0 ° n 2 = 1 sin θ c

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the sc…
