As shown in the figure, light is incident normally on one face of the prism. A liquid of refractive index
μ is placed on the horizontal face
AC. The refractive index of prism is
3/2. If total internal reflection taken place on face
AC,
μ should be less than
I√34, where
I is an integer. Find the value of
I.
