Question

A student 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.

1. State the type of the mirror.
2. Find the linear magnification
3. Find the distance b/w the object and the mirror
4. Draw a ray diagram to show the image formation.

Answer 1

1) Concave mirror
2) Linear Magnification m = -v/u 
u = -15 cm
v = -60 cm
m = -v/u = -60/15 = -4
3) 15 cm
4) Ray diagram - object between F and C.
