When the object is at centre of curvature of a concave mirror, its image is formed at the centre of curvature. ____

Define the principal focus of a concave mirror.

STATEMENT - 1 : Image formed by a convex mirror is always virtual, erect and diminished. STATEMENT - 2 : In case of a convex mirror the image is erect and virutal, when the object is placed between focus and pole. STATEMENT - 3 : In case of a concave mirror the image is real, when the object is placed between focus and centre of curvature.

A point object 'O' is at the center of curvature of a concave mirror. The mirror starts to move at a speed u, in a direction perpendicular to the principal axis. Then, the initial velocity of the image is

The image formed by a concave mirror

A real 1 mm long object is kept perpendicular to the principal axis of a concave mirror. The size of the image formed is 1/4 mm. Now the mirror starts moving, away, from the object with a velocity 2 cm/s along the principal axis.

If the distance between the virtual image from Its real object is 60 cm in case of a concave mirror . The focal length of the concave mirror If the image formed is 3 times magnified image is

It is desired to obtain an erect image of an object, using concave mirror of focal length of 12 cm. (i) What should be the range of distance of an object placed in front of mirror ? (ii) Will the image be smaller or large than the object ? Draw a ray diagram to show the formation of image in this case. (iii) Where will the image of this object be, if it is placed 24 cm in front of the mirror ? Draw a ray diagram for this situation also to justify your answer. Show the positions of the pole, the principal focus and the centre of curvature in the above ray diagrams.

A kid of height 1.1 ft is sleeping straight between focus and centre of curvature along the principal axis of a concave mirror of small aperture. His head is towards the mirror and is 0.5 ft from the focus of the mirror. How a plane mirror should be placed so that the image formed by it due to reflected light from concave mirror looks like a person of height 5.5 ft standing vertically. Draw the ray diagram. Find the focal length of the concave mirror.

(a) Draw the ray diagram for the formation of image of an object by a convex mirror and use it (along with the sign convention) to derive the mirror formula. (b) Use the mirror formula to show that for an object, kept between the pole and focus of a concave mirror the image appears to be formed behind the mirror.
