Draw a ray diagram to show image formation by plane mirror of a finite sized objec

Sure, here are the steps to draw a ray diagram to show image formation by a plane mirror of a finite sized object:

1. Draw a straight line to represent the mirror. Label it as 'M'.

2. Draw a perpendicular line at one end of the mirror to represent the normal line.

3. Draw an object in front of the mirror. You can represent the object as an arrow. Label it as 'AB'. Point 'A' should be the top of the object and 'B' the bottom.

4. Draw a line (incident ray) from the top of the object 'A' to the mirror. This line should be at an angle to the normal line.

5. At the point where the incident ray meets the mirror, draw another line (reflected ray) equal in angle to the incident ray but on the other side of the normal line. Extend this line behind the mirror.

6. Repeat steps 4 and 5 for the bottom of the object 'B'.

7. The point where the reflected rays meet or appear to meet is where the image of the object is formed. Label this as 'A'B''.

8. The image formed by a plane mirror is always virtual, upright, and of the same size as the object.

Remember, in a ray diagram, the object and image are usually represented by arrows, rays are represented by straight lines with arrows to show the direction of light, and the mirror is represented by a straight line with dashes to represent the reflective side.
