Question

find the magnification of the convex lens . object of height 9cms and the image height is 36cm:​

Answer 1

$\huge{\underline{\sf Solution:-}}$

Here

• Object height=9cm=h
• Image height=36cm=h'

We know that

$\boxed{\sf Magnification =\dfrac{h'}{h}}$

$\\ \tt{:}\longrightarrow Magnification=\dfrac{36}{9}$

$\\ \tt{:}\longrightarrow Magnification=4$

Hence

Image is 4times bigger than the object.
