Question

Find the height of the retinal image of a person 2.0 m tall, standing 8.20 m away.

science physics

Answer 1

Answer #1

Solution)

We know,

Magnification, m=-di/do

Also,

M= hi/ho

So, hi/ho=-di/do

Hi= (-di/do)*ho

Given, do=2m

Ho=8.2 m

So, hi=(-0.025 m/2m)*8.2=-0.1025 m=-10.25 cm

Here, negative sign indicates that the image is inverted.
