A student want to project the image of a candel flame on a screen 48cm in front of mirror by keeping the flame at a distance of 12cm from the pole suggest the type of mirror should be use find linnearmagnification of the image how far is the image from the object draw a ray diagram to show the image formation
Answers
He should use a Concave mirror because only concave mirror forms a real image.
Given: u= -12 cm
v= -48 cm
Using mirror formula:
1/v + 1/u = 1/f
=1/-48 + 1/-12 = 1/f
=(1+4)/-12 = 1/f
=5/-12 = 1/f
=f = -12/5 = -2.4 cm
So, the focal length of the concave mirror is 2.4cm.
Magnification:
Magnification = -v/u
= -(-48)/(-12)
= -3
So, the magnification of the image is -3.
______________________________________
Distance of image from object =48-12
=36cm.

Answer:
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.
(i) Suggest the type of mirror he should use.
(ii) Find the linear magnification of the image produced.
(iii) How far is the image from its object ?
(iv) Draw ray diagram to show the image formation in this case.
Answer:-
(i) He should use a concave mirror, as it forms a real image on the same side of the mirror.
(ii) Object distance, u=-12cm
Image distance, v=-48 cm
Magnification, m=-v/u=-(-48)/(-12)=-4
The minus sign in magnification shows that the image formed is real and inverted.
(iii) The image is formed at a distance of 35 cm from the object.
(iv) ray diagram in attachment.
In this case, the image is formed beyond the center of curvature. This image is real, inverted and enlarged.
