Question

A mirror forms real and magnified image at distance 20 CM. If ROC is 30cm find the position of object & magnification.​

Answer 1

Answer:

u=−30cm and magnification m=(−v/u)=−3 so v=(3u)

image is real so m should be negative v should be negative so v=−90cm

putting the above values of v and u in the Mirror equation,

f

1

=

u

1

+

v

1

we get focal length f=−22.5cm and image position v=−90cm
