If an object far away from a convex mirror moves towards the mirror, the image also moves. Does it move faster, slower or at the same speed as compared to the object ?

An image of a linear object due to a convex mirror is 1/4 th of the length of the object . If focal length of the mirror is 10 cm , find the distance between the object and the image. The linear object is kept perpedicular to the axis of the mirror.

A 4.5 cm needle is placed 12 cm away from a convex mirror of focal length 15 cm. Give the location of the image and the magnification. Describe what happens as the needle is moved farther from the mirror.

Two tuning forks with natural frequencies of 340 Hz each move relative to a stationary observer. One fork moves away form the observer, while the other moves towards him at the same speed. The observer hears beats of frequency 3 Hz . Find the speed of the tuning fork.

If image obtained from concave mirror of focal length f is (1/n)^(th) times of object, then find object distance.

If real image obtained from concave mirror of focal length f is n times of object, then find object distance.

A slab of glass, of thickness 6 cm and refractive index mu =1.5 is placed in front of a concave mirror. If the radius of curvature of the mirror is 40 cm and the reflected image coincides with the object, then the distance of the object from the mirror is

A plane mirror is moving with velocity -2 hati - 3 hatj + 4hatk . A point object in front of the mirror move with a velocity -3 hati + 4 hatj -4hatk . There hat j is along the normal to the plane mirror and facing towards the object. Find velocity of image.

Object is placed 60 cm away from convex mirror. If magnification is 0.5, image distance = …....

A real image obtained by a concave mirror is 4 times bigger than the object. If the object is displaced by 3 cm away from the mirror, the image size becomes 3 times the object size. Find the focal length of the mirror.
