Q15 of 60 Page 1

A student wants to project the image of a candle flame on a screen 60 cm in front of a mirror by keeping the flame at a distance of 15 cm from its pole.

(i) Write the type of mirror he should use.


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


(iii) What is the distance between the object and its image?


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

(i) He should use a concave mirror.


(ii) The linear magnification is given by the relation: m = -v/u





m=-4


(iii)The distance between the object and the image is: 60- 15 =45 cm.


(iv)The Ray diagram is as follows:



The nature of the image formed is: real, inverted, magnified and beyond 2f .
