## Answers ( )

1. Answer:

Choose all correct statements: For the angle of incidence 45° (for A and B pair) and 35° ( for A and C pair) in medium A, the angle of refraction in medium B is equal to angle of refraction in medium C. * –

1]Medium C is rarer than medium B .

2]Refractive index of medium C with respect to medium B = sin 35°/sin 45° .

3]When light travels from B to C, it bends away from the normal . 4]Medium A is the most dense among A, B and C
