The critical angle at the boundary between a ruby and the air is 34.6º. Use this to calculate the refractive index of this ruby. Give your answer to
two decimal places.​

Respuesta :

Answer:1.8

Explanation:

Critical angle=c=34.6

Refractive index =n

n=1/sinc

n=1/sin34.6

n=1/0.5678

n=1.8

Refractive index is 1.8
