A student, Mirra wants to project the image of a candle flame on a screen 60cm in front of a mirror by keeping the flame at a distance of 15cm from its pole.
(i) Write the type of mirror Mirra should use.
(ii) What is the distance between the object and its image?
Mira wants to project the image of a candle flame on a screen 60cm in front of a mirror by keeping the flame at a distance of 15cm from its pole.
The image must be real and it is should be formed 60cm in front of a mirror.
(i) Mira should use a concave mirror, as it forms a real image in front of the mirror on the same side of the object.
(ii) The flame is 15 cm from the pole and the object is at 60 cm. So, the distance between object and image is:
60 -15 = 45 cm
