Question

Determine the image distance for an 11.3 m tall object placed 45.0 m from a concave mirror having a focal length of 83.1 m. *

Answer 1

Answer

Using formula

$\frac{1}{f}=\frac{1}{v}+\frac{1}{u}$

$\frac{1}{(-83.1)}=\frac{1}{v}+\frac{1}{(-45)}$

After calculation

$v=\frac{3739.5}{38.1}=98.14m$
