The diagram shows a point source of light S, a convex lens L and plane mirror M. These are placed such that rays of light from S return to it after reflection from M.

What is the distance OS called?

The diagram shows a point source of light S, a convex lens L and plane mirror M. These are placed such that rays of light from S return to it after reflection from M. To which point (left of S or right of S) will the rays return, if M is moved to the left and brought in contact with L?

A point source of light is placed in front of a plane mirror.

A ray of light after reflection from a mirror is known as

The distance between a convex lens and a plane mirror is 10 cm. The parallel rays incident on the convex lens after reflection from the mirror form image at the optical centre of the lens. Focal length of lens will be

The distance between a convex lens and a plane mirror is 10 cm. The parallel rays incident on the convex lens after reflection from the mirror forms image at the optical centre of the lens. Focal length of lens will be

A point source of light is placed in front of a plane mirror as shown in Figure. Determine the length of reflected path of light on the screen Sigma

In the shown figure, mirror is rotated by an angle theta. Find theta if ray of light retraces its path after reflection from M ray of light MP turns in the direction of MN.

A ray of light passing through the focus, after reflection from a concave mirror travels ……….

Mention one difference between reflection of light from a plane mirror and total internal reflection of light from a prism.

L is a lens such that a parallel beam of light I ncident on it, after refraction, converges to a point at a distance x from it and M is a mirror such that a parallel lbeam of light incident on it, after reflection, converges to a point at a distance y from it. Now the lens L and mirror M are placed at a distan 2(x+y) from each other. An object of size 2 cm is kept infront of lens at a distance 2x from it. Find the nature, position , and size of the image that willl be seen by an observer looking toward the mirror through the lens.
