A parabola mirror is kept along `y^2=4x` and two light rays parallel to its axis are reflected along one straight line. If one of the incident light rays is at 3 units distance from the axis, then find the distance of the other incident ray from the axis.

Find the distance CQ if incident light ray parallel to principal axis is incident at an angle i. Also, find the distance CQ if irarr0 .

Figures shows a plane mirror on which a light ray is incident, if the incident light ray is turned by 10^(@) and the mirror by 20^(@) as shown , find the angle turned by the reflected ray.

A ray of light is incident on a concave mirror . It is parallel to the principal axis and its height from principal axis is equal to the focal length of the mirror. The ratio of the distance of point B to the distance of the focus from the centre of curvature is (AB is the reflected ray)

A ray of light is incident on a plane mirror, making an angle 'q' with the surface of the mirror. Arrange the following steps in sequential order to calculate the angle between the incident light ray and the reflected light ray. (A) Draw a normal line on the plane mirror at the point of incidence of the light ray. (B) Note down the angle between the plane mirror and the incident light ray. (C) The sum of the angle of incidence and the angle between the plane mirror and the incident ray is 90^(@) .Determine the angle of incidence. (D) From the laws of reflection, the angle of incidence is equal to the angle of reflection. Then the sum of the angle of incidence and the angle of reflection gives the angle between the incident light ray and the reflected light ray.

A ray of light along x+sqrt(3)y=sqrt(3) gets reflected upon reaching x-axis,the equation of the reflected ray is
