1.	A plane wavefront is travelling from air to glass. It is incident at an angle of incidence of 45∘ on the glass surface. If the ratio of width of wavefront in air to that in glass is √2√3, find the refractive index of glass.
Answer» A plane wavefront is travelling from air to glass. It is incident at an angle of incidence of $45^{\circ}$ on the glass surface. If the ratio of width of wavefront in air to that in glass is $\frac{\sqrt{2}}{\sqrt{3}}$ , find the refractive index of glass.

suppose there is a point object in front of a plane mirror. one incident ray from this point strikes mirror and reflect. Another light ray comes from some height which is above than the pointed object, strike the mirror and reflect. but when we extend first and second reflected ray it intersect at a point. will the image of the pointed object will form there. if not, why.
