Here is Your Answer
CONCAVE MIRROR
A concave mirror is a mirror with a curved reflecting surface which is bulging inwards or curved inwards. It is also known as a converging mirror as this reflecting surface collects light incident on its surface, and reflects the parallel rays of light towards a common focus. It can be thought to have been made from the inside of a sphere which has been silvered on the inside. In this knowledge article, we shall get acquainted with some of the uses of concave mirror.
There are two rules of reflection of light when it comes to concave mirrors. They are:
● Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection.
● Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.
● Any ray passing through the centre of curvature of the mirror will reflect back along its own path since the radius of a circle always hits the edge of the circle at 90 degrees – it hits it normally so the angle of incidence and reflection will both be zero.
