Question 35 POST_UTME_UI • 2017 • PHYSICS • objective

A light source is placed at a dis\tance $d$ from a convex lens of focal length $f$. If the lens is placed in a medium of re\fractive index $n_1$ and the surrounding medium has a re\fractive index $n_2$, find the location of the image formed by the lens.

Answer Options

Correct Answer A. \frac{1}{f} = \frac{1}{d} + \frac{1}{d'}
B. \frac{1}{f} = \frac{1}{d} - \frac{1}{d'}
C. \frac{1}{f} = \frac{n_2}{n_1} \frac{1}{d} + \frac{1}{d'}
D. \frac{1}{f} = \frac{n_1}{n_2} \frac{1}{d} - \frac{1}{d'}
Correct Answer
A
Correct Option:
\frac{1}{f} = \frac{1}{d} + \frac{1}{d'}
