Question

When a concave mirror is placed facing the sun, the sun’s rays converge to a point 10 cm
from the mirror. Now an erect, 2 cm long pin is placed 15 cm away on the principal axis
of the mirror. If you want to get the images of the pin on a card, where would you place the
card ? What would be the nature and height of the image

Answer 1

Answer:

is it correct

Explanation:

Since candle flame is placed at the centre of curvature [as object distance is 20 cm which is twice of focal length i.e. center of curvature C], so the image will be formed at C. So screen will be placed 20 cm from the mirror on the same side of the object. Size of the image will be same as the size of object = 2 cm.
