Question:medium
On a hypotenuse of a right angled prism of liquid is placed as shown in the figure. Light is allowed to fall normally on the short face of the prism. In order that the ray of light may be totally reflected, the maximum value of refractive index is
On a hypotenuse of a right angled prism of liquid is placed as shown in the figure. Light is allowed to fall normally on the short face of the prism. In order that the ray of light may be totally reflected, the maximum value of refractive index is
Show Hint
Total internal reflection occurs only when light travels from denser to rarer medium.
