SamplePhysics· MCQ+4 / -1

A transparent block A having refractive index

μ = 1.25

is surrounded by another medium of refractive index

μ = 1.0

as shown in the figure. A light ray is incident on the flat face of the block with incident angle

θ

as shown in the figure. What is the maximum value of

θ

for which light suffers total internal reflection at the top surface of the block?

$Ray diagram of a light ray entering the left vertical face of a rectangular transparent block A at incidence angle theta, bending toward the top surface, and reaching the top surface at angle theta-c where it undergoes total internal reflection and travels along the surface. The surrounding medium is labelled refractive index 1.0 and the block is labelled refractive index 1.25.$

A. $sin^{- 1} (\frac{3}{4})$
B. $tan^{- 1} (\frac{4}{3})$
C. $cos^{- 1} (\frac{3}{4})$
D. $tan^{- 1} (\frac{3}{4})$
