Question

A diamond is immersed in a liquid with a refractive index greater than water. Then the critical angle for total internal reflection will​

Answer 1

Explanation:

given : na = 1.00.

ND = 2.42

for total reflection to occur the incident angle must be greater than critical angle.............

critical angle of diamond= sin- 1

(. ND

NA) = sin. i.e.

(2.42 1.00)= 24. o

thus smallest angle for intial reflection is 24.o

Answer 2

answer is Increases.......
