Question

the refractive index of Glass with respect to air is 2 then the critical angle of Glass air interface is​

Answer 1

Answer:

critical angle=30 degrees

Explanation:

refractive index= sin r/ sin i

critical angle=

2= sin 90/ sin c

2=1/sin c

sin c= 1/2

c= 30

in this case the light goes through the glass and refracts at an angle of 90 degrees in the air. So we use the formula of refraction from denser to rarer medium and put in the available values.

i=c

angle of refraction=90

refractive index= 2

Answer 2

Answer:

answer is 30 degrees.
