A ball is dropped from rest 3.0 m directly above the vertex of a concave mirror that has a radius
of 1.0 m and lies in a horizontal plane.
(a) Describe the motion of ball's image in the mirror
(b) At what time do the ball and its image coincide?

A ball swings back and forth in front of a concave mirror. The motion of the ball is described approximately by the equation x= f cos (omega)t , where f is the focal length of the mirror and x is measured along the axis of mirror. The origin is taken at the centre of curvature of the mirror. (a) Derive an expression for the distance from the mirror of the image of the swinging ball. (b) At what point does the ball appear to coincide with its image? (c) What will be the lateral magnifiaction of the image of the ball at time t= T/2 , where T is time period of oscillation?

The sum subtends an angle 0.5^(@) at the center of a concave mirror having radius of curvature 1 m. What will be the diameter of the image of the sun formed by the mirror?

A thin lens of focal length +10.0 cm lies on a horizontal plane mirror. How far above the lens should an object be be held if its image is to coincide with the object?
