Q30 of 223 Page 198

A man holds a spherical shaving mirror of radius of curvature 60 cm at a distance of 15 cm, from his nose. Find the position of image, and calculate the magnification.

Radius of curvature, R=-60cm

F = R/2 = 60/2 = 30cm


f=-30cm, u=-15cm


We have



So, the image is formed 30 cm behind the mirror and the magnification is +2.

An object is placed (a) 20 cm, (b) 4 cm, in front of a concave mirror of focal length 12 cm. Find the nature and position of the image formed in each case.

 29

A concave mirror produces a real image 1 cm tall of an object 2.5 mm tall placed 5 cm from the mirror. Find the position of the image and the radius of curvature of the mirror.

 31

An object is placed just outside the principal focus of concave mirror. Draw a ray diagram to show how the image is formed, and describe its size, position and nature.

If the object is moved further away from the mirror, what changes are there in the position and size of the image ?
