Question

calculate the critical angle for a dimand its refeative been 2.42​

Answer 1

Actually this is the full question:

Calculate the critical angle for diamond having a refractive index of 2.42 and Crown glass having a refractive index of 1.52.

Answer:

41.14°

Explanation:

Let the refractive index of air be 1

For diamond

μdiamond sinC=μair sin90°

2.42sinC=1

Critical angle for diamond is C=24.4°

For crown glass

μcrown sinC1=μair ssin90

1.52 sinC1=1

Critical angle for crown glass is C1=41.14°
