A ________ image cannot be obtained on a screen.
The diagram in Fig. shows an incident ray AO and the reflected ray OB from a plane mirror. The angle AOB is 30°. Draw normal on the plane mirror at the point O and find:
How many images are formed for a point object kept in between two plane mirrors at right angles to each other? Show them by drawing a ray diagram.
Two plane mirrors are arranged parallel and facing each other at some separation. How many images are formed for a point object kept in between them? Show the formation of images with the help of a ray diagram
