Question

a 4cm object is placed perpendicular to the principal axis of a convex mirror of focal length 7.5cm .the distance of the image from the mirror if it is 0.6cm in size is 51/x then x​

Answer 1

Answer:x= 51cm

Explanation:

Find the value of u from the mirror formula,

Note for converted mirror f is negative and V is negative

which results u = 0.6cm,

Then M = hi/ho= V/u

f = 7.5cm

V=0.6cm

image formed = 51/X =M

then 51/X = V/u

x = 51cm
