Vedclass · Answer

(C) The number of images $n$ formed by two plane mirrors inclined at an angle $	heta$ is given by the formula $n = \frac{360^{\circ}}{	heta} - 1$, provided that $\frac{360^{\circ}}{	heta}$ is an even integer.Given $	heta = 72^{\circ}$.Calculating the ratio: $\frac{360^{\circ}}{72^{\circ}} = 5$.Since $5$ is an odd integer, the formula depends on the position of the object. Assuming the object is placed symmetrically, the number of images is $n = \frac{360^{\circ}}{	heta} - 1 = 5 - 1 = 4$.Therefore, the number of images is $4$.

Two plane mirrors are inclined at an angle of $72^{\circ}$. The number of images of a point object placed between them will be
