Question

An object is placed between two identical convex
mirrors X and Y of focal length 15 cm at the mid
point on their common principal axis. If the two
mirrors are separated by a distance of 20 cm, deter-
mine the distance of the first two images formed in
the mirror Y​

Answer 1

Answer:

First image will form at distance d = 6 cm behind mirror X and second image will form at distance d = 9.51 cm behind mirror Y

Explanation:

Object is placed between two convex mirror

Now for the first image from mirror x we have

$d_o = 10 cm$

$f = 15 cm$

now by mirror formula we have

$\frac{1}{d_i} + \frac{1}{d_o} = \frac{1}{f}$

so we have

$\frac{1}{d_i} + \frac{1}{-10} = \frac{1}{15}$

$d_i = 6 cm$

Now for Mirror Y we can say

$d_o = 20 + 6 = 26 cm$

again by same formula

$\frac{1}{d_i} + \frac{1}{d_o} = \frac{1}{f}$

so we have

$\frac{1}{d_i} + \frac{1}{-26} = \frac{1}{15}$

$d_i = 9.51 cm$
