A ray of light incident on the horizontal surface of a glass slab at 70^@ just grazes the adjacent vertical surface after refraction. Complete the critical angle and refractive index of glass.

Which of the following statement is // are correct about the refraction of light from a plane surface when light rays is incident in denser medium. [ C is critical angle ]

" Relation b/n refractive index of denser medium and critical angle is "

A ray of light incident on the horizontal surface of a glass slab at an angle of incidence ‘i’just grazes the adjacent vertical surface after reflection. Compute the critical angle and refractive index of glass
