Answer 1

Answer:

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.

Answer 2

Answer:

The type of the mirror is Concave mirror

Linear Magnification of the image produces (m) = -v/u 

u = -20 cm

v = -80 cm

m = -v/u = -80/-20 = 4

The distance b/w the object and the mirror is 20 cm.
