Question

Define critical angle and determine the refractive index of benzene if the critical angle is 45°

Answer 1

Hey friend

here is your answer

Critical angle can be defined as the angle of incidence when the angle of refraction is 90°.

[tex]refractive \: \: index ( n ) = \frac{1}{ \sin(c) } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ={ \sqrt{2} } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = { \sqrt{2} }
