A small silver Christmas ball with a diameter of 6.25 cm was hanging on a Christmas tree. The Christmas ball was 0.40 m away from you, and you saw your reflection on its surface. Assuming that your height is 1.5 m, where and how tall is your image on the Christmas ball? Is it erect or inverted? Is it real or virtual?

When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
