A concave mirror (with center indicated) has a radius of curvature of 40 cm. An object with a height of 4 cm is placed 60 cm away from it, along the axis. (a) Sketch the principal rays (in MS paint, say) and classify the image produced from the mirror. (b) Where is the image located? (c) What is its height? (
Applications Of Reflection Of Light
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.
