Question

In a particular medium, angle of incidence of light is 45 degree and angle of refraction is 30 degree . What will be the refractive index of that medium? Please tell...​

Answer 1

Answer:

We know, Refractive index=sin i/sin r

=sin45 deg / sin30 deg

=1/root2 /1/2 (since sin45 Deg =1/root2 & sin 30 deg=1/2)

= 2/root2

=root2

Therefore, The required refractive index is root2
