The figure shows the path of a ray passing through an equiangular prism PQR. It is incident on face PR at angle slightly greater than the critical angle for total internal reflection . If the angle alpha shown in the figure is 30^(@) . Calculate the R.I. of the material of the prism.

If the critical angle for total internal reflection from a medium to vacuum is 30^(@) , the velocity of light in the medium is

Define critical angle for total internal reflection and write its relation with refractive index.

If the critical angle for total internal reflection from a medium to vacuum is 45^@ , then velocity of light int he medium is,

If the critical angle for total internal reflection from a medium to vacuum is 30^(@) , the velocity of light in the medium is
