Determine the size, position and nature of the image of an object 5.0 cm tall, placed on the principal axis of a concave mirror of focal length 15 cm, at a distance 35 cm from the mirror.

Answers

Let 1 cm represent 5 cm.
Then the focal length is 3 cm.
Object distance = 7 cm, object height = 1 cm.

From the scale drawing, Image position = 5.4 cm × 5 = 27 cm in front of the mirror.
Image size = 0.75 cm × 5 = 3.75 cm.
Image is real and inverted.
