Q10 of 60 Page 1

A student wants to project the image of a candle flame on a screen 48 cm in front of a mirror by keeping the flame at a distance of 12 cm from its pole.

(a) Suggest the type of mirror he should use.


(b) Find the linear magnification of the image produced.


(c) How far is the image from its object?


(d) Draw ray diagram to show the image formation in this case.

(a) He should use concave mirror because only concave mirrors produces real images.

(b)Given: Object distance, u = -12 cm


Image distance, v =-60 cm


Linear magnification of the image can be expressed as follows:




m=-4


(e) The Ray diagram is as follows:
