(Reflection of light on a plane mirror)

Plane Mirror

Images in plane mirrors

  1. Figure to the right shows how, by reflecting light, a plane mirror forms an image of a point source of light such as a small light bulb.
  2. The image forms in a mirror is
    1. Upright
    2. Virtual
    3. Laterally inverted
    4. Same size as the object

Steps to draw a ray diagram for an image in a plane mirror 

    Step 1

    Draw the virtual image. Distance of object = Distance of image )

    Step 2

    Draw 2 reflected rays, one from the image to the top of the eye and the other one from the image from the bottom of the eye. )

    Step 3

    Draw the respective incident rays for the reflected rays you draw in step 2. )
