A light ray is incident perpendicularly to one face of a `90^circ` prism and is totally internally reflected at the glass-air interface. If the angle of reflection is `45^circ`, we conclude that the refractive index n

A light ray is incident perpendicular to one face of a 90^@ prism and is totally internally reflected at the glass-air interface. If the angle of reflection is 45^@ , we conculde that for the refractive index n as

The path of a ray of light passing through an equilateral glass prism ABC is shown in figure. The ray of light is incident on face BC at the critical angle for just total internal reflection. The total internal reflection. The total angle of deviation after the refraction at face AC is 108^@ . Calculate the refractive index of the glass.

White light is incident on the interface of glass and air as shown in the figure. If green light is just totally internally reflected then the emerging ray in air contains

At what angle should a ray of light be incident on the face of a prism of refracting angle 60^(@) so that it just suffers total internal reflection at the other face ? The refractive index of the material of the prism is 1.524.
