Two plane mirrors are inclined to each other at some angle. A ray of light incident at an angle of $30 °$ on one of the mirrors, after reflection from the other, retraces its path. The angle (in degree) between the mirrors

Answer:

30.00

Solution:

$∠ i = ∠ r = 3 0^{o}$

$∴ ∠ OIQ = 6 0^{o}$

$∴ ∠ IOQ$ $= 9 0^{o} - 6 0^{o} = 3 0^{o}$
