# Bending of rays

A ray of light is incident making an angle $$\theta$$ with the axis on one plane end of a transparent cylindrical fiber as shown in the figure. It is observed that for $$\theta>45^{o}$$, the ray of light entering the cylinder, will come out of the curved surface The refractive index of the material of the cylinder up to two decimal places

Take $$\sqrt{3}=1.732$$ and $$\sqrt{2}=1.414$$
