Show by ray diagram the formation of image of an object placed at the focus of a concave mirror.

Show by ray diagram the formation of image of an object placed at the center of curvature of a concave mirror.

The size of the image of an object placed at the focus of a concave mirror is ………….. .

(a) To construct a ray diagram, we use two rays which are so chosen that it is easy to know their directions after reflection from the mirror. List two such rays and state the path of these rays after reflection in case of concave mirrors. Use these two rays and draw ray diagram to locate the image of an object placed between pole and focus of a concave mirror. (b) A concave mirror produces three times magnified image on a screen. If the object is placed 20 cm in front of the mirror, how far is the screen from the object?

Draw ray diagram to show the: formation of image when object is placed in front of a concave mirror? between centre of curvature and focus.

Draw ray diagram to show the image formation of image when object is placed in front of a concave mirror between pole and focus.

With the help of a ray diagram, show the formation of an image of an object placed between principal focus and centre of curvature of a concave mirror.
