A concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it. Where is the image located?
A candle is kept at a distance of 20cm in front of a concave mirror of focal length 10cm.
During a science exhibition a student wants to project the image of a candle flame on a screen 80 cm in front of a mirror by keeping the candle flame at a distance of 20 cm from its pole.
Find the magnification of the image formed by a spherical mirror from the following data : u = − 20 cm, f = − 15 cm.
Draw a labelled ray diagram for the image formation by a concave mirror when an object is placed between its centre of curvature and focus.
The image formed by a concave mirror of focal length 25 cm is real and of magnification -1. In this case the distance between the objet and its own image is:-
