Q

What are the four rules of reflection in a curved mirror?

A

A light Ray parallel to the principal axis is reflected through the focus

A light Ray through the focus reflects parallel to the principal axis

A light Ray through the centre of curvature is reflected back on the same line

A light Ray through the vertex is reflected at the same angle
