a ray of light travelling in air strikes the glass surface at an angle of incidence 60 degree..find the angle of refraction if refractive index is 3/2...
Help plz

90-60=30
30=3/2
30×2=3
60/3=20
30=3/2
30×2=3
60/3=20

answer is 45degree

Refractive index doesn't matter here. We all know that the angle of incidence is always equal to the angle of reflection.... Same applies for-
"THE ANGLE OF INCIDENCE IS ALWAYS EQUAL TO THE ANGLE OF REFRACTION".
Therefore, angle of reaction = 60°
Hope this helps...

no
i think so...
Snell’s Law states that- there is a constant relation between the angle of incident ray ( i ) and angle of refracted ray ( r ). This constant is the refractive index of second medium relative to the first medium.

Where n 1 is the refractive index of first medium i.e. air here and n 2 is the refractive index of second medium i.e. glass slab here, v 1 is the speed of light in first medium and v 2 is the speed of light in second medium.
.. i think this can also be the answer
