Question

If object subtends an angle $\theta =$ of ${0.5}^0$ on the eye then angle subtended by its image is

• A. $2^0$
• B. $3^0$
• C. $5^0$
• D. $4^0$

Answer 1

The correct option is D $4^0$

We have already estimated the AM to be equal to 8
Now, m = $\frac{\theta }{{\theta }_o}$
with ${\theta }_o=0.5$
$\theta$ comes out to be 4
