The magnification of an image is +1.5 and the object distance is 30 cm from a spherical mirror. The image is formed at ______________.
The correct answer is (c) 45 cm behind the mirror
Explanation: The magnification (M) produced by a mirror is the ratio of the height of the image to the height of the object. It can also be related to the object and image distances:
M=
thus, Image distance = M x Object distance= 1.5 x 30 = 45 cm behind the mirror.

The focal length of a small concave mirror is 2.5 cm. In order to use this concave mirror as a dentist's mirror, the distance of tooth from mirror should be
When an object is placed at the centre of curvature in front of a concave mirror, the characteristics of the image formed are:
The radius of curvature of a plane mirror is
If an image formed after reflection from a mirror is virtual and high diminished, then the position of the object and type of mirror is:
Magnification produced by a spherical mirror is equal to:
Suppose Ram has placed a ball in front of a concave mirror of focal length (f )at various distances (u) and he has measured the corresponding image distances (v). From the values of u and v, Ram is able to plot a graph of 1/v against 1/u. From the graph, Ram has observed that x intercept and y intercept are 0.1" " cm and 0.11" " cm, respectively. Then the focal length of the mirror is:
An object of height 3 cm is placed at a distance 30 cm in front of a convex lens of focal length 20 cm. The height of the image will be:
