Q6 of 10 Page 107

An object of height 3 cm is placed in front of a convex lens of focal length 10 cm at a distance of 15 cm.

What is the height of the image?

From the formula of magnification


So, Height of image (hi) = Height of object (ho)


Here height of object ho is: + 3 cm


Height of image (hi) =


Height of image (hi) =
