The side view mirror in a car is a convex mirror. The radius of curvature of the mirror is 6 m. The car is 18m behind you. What is the height of a 1.5 m high vehicle would appear to you when you see its image on the mirror? Draw a ray diagram to show the image formation.
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.
The side view mirror in a car is a convex mirror. The radius of curvature of the mirror is 6 m. The car is 18m behind you. What is the height of a 1.5 m high vehicle would appear to you when you see its image on the mirror? Draw a ray diagram to show the image formation.
Given information:
Here, R is curvature’s radius of the convex mirror, u is the object distance and ho is the object’s (vehicle) height.
The standard sign convention is used.
Consider the diagram below.
Write the radius of curvature (R) and focal length (f) relation and plug the required values to determine the focal length.
Write the mirror formula and plug the required values to determine the image’s distance (v).
