An object of height 2.5 cm placed perpendicularly on the principle axis of a concave mirror of focal length f at a distance of `3/4f`. What will be the nature of the image of the object and its height?

An object of height 2.5cm is placed perpendicularly on the principal axis of a concave mirror of focal length f at a distance of (3)/(4)f . What will be the nature of the image of the object and its height?

An object is placed perpendicularly on the principal axis of a concave mirror of focal length 25 cm and an image is formed at a distance of 100 cm in front of the mirror. Determine the position of the object and mangnification of the image.

If an object of height l is placed perpendicularly on the principal axis of a spherical mirror at a distance u from it, prove that the height of its image, l' = l((f)/(u-f))

A 2.0cm tall object is placed 15cm in front of a concave mirror of focal length 10cm. What is the size and nature of the image?

An object of length 5cm is placed perpendicularly on the principal axis at a distance of 75cm from a conacave mirror. If the radius of curvature of the mirror is 60cm, calculate the image distance and its hieght.

A concave mirror of focal length 15 cm forms an image twice the size of the object. If the image is virtual, the distance of object is

The focal length of a concave mirror is 30 cm. An object is placed at a distance of 45 cm in front of the mirror. A plane mirror is placed perpendicularly on the principal axis of the concave mirror in such a way that the object is situated in between the two mirrors. Light rays from the object at first are reflection from the concave mirror and then from the plane mirror. As a result the final image coincides with the object. What is the distance between the two mirros?

A rod of length 10 cm lies along the principal axis of a concave mirror of focal length 10 cm in such a way that its end closer to the pole is 20 cm away from the mirror? What is the length of the image?
