Question

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.(All India - 2014)

Answer 1

Answer:

Hey write short questions because I am not your DAD

Answer 2

Let us solve for it

Explanation:

Image distance (v)=60cm = -60cm

Object distance (u)=15cm = - 15cm

The mirror he should use --> concave mirror

(b)

$m=-v/u\\m=-(-60)/-15\\m = -4$

(c) The distance between the object and its image is 45 cm

The ray diagram is attached below .
