# How to Draw a Ray Diagrams for Convex Mirrors

## Instructions

• 1

The Basic Ray Diagram

Draw a basic ray diagram and choose a point to mention the object. From the top of the object, draw two rays such that one ray passes through the focal point (if produced), while the other travels straight towards the mirror and is parallel to the principal axis. Do put arrows on the two rays to indicate their direction of travel.

Applying Laws of Reflection

Now following the laws of reflection, reflect the two rays. Make sure the ray that travels towards the focal point is reflected parallel to the principal axis, while the other ray that was parallel to the principal axis  is reflected in such a direction that its extension passes through the focal point. Draw arrow heads to show the travel direction and make the rays appear to be diverging from the mirror.

The location of Image formed

After that, produce the two reflected rays at the back of the convex mirror such that they intersect somewhere before the focal point. The point of intersection of the two produced rays will be the point where the image is located. The same procedure can be tried with different positions of the object.
