Question

a 4 cm tall 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 where x is​

Answer 1

Answer:

Explanation:

Answer

The magnification is given as,

m=−uv​

0.6=−uv​

The mirror formula is given as,

v1​+u1​=f1​

0.6u1​−u1​=f1​

u=5cm

Thus, the distance from the mirror is 5cm.
