Incident ray from focus S after reflection by ellipse at point P passes through the other focus S'.

Answer the following questions : In the case of a convex lens , show the path of the refracted ray when the incident ray of light is parallel to the principal axis of the lens passes through the focus of the lens passes through the optical centre of the lens.

In the case of a convex lens, show the path of the refraction ray when the incident ray of light (1) is parallel to the principal axis of the lens (2) passes through the focus of the lens (3) passes through the optical centre of the lens.

A ray of light passing through the point (1,2) is reflected on the x-axis at a point P and passes through the point (5,3) , then the abscissa of the point P is-

Answer the following questions: In the case of a concave mirror, show the path of the reflected ray when the Incident ray of light passes through the focus of the mirror

Prove that normal at any point (except vertex) of ellipse does not pass through the focus.

If an incident ray passes through the focus, the reflected ray will

If an incident ray passes through the focus, the reflected ray will
