Two plane mirrors are placed making an angle $θ^{\circ}$ in between them. For an object placed in between the mirrors, if angle is gradually increased from $0^{\circ} to 180^{\circ}$ , how will the number of images change: increase, decrease or remain unchanged?

Solution

Two plane mirrors are placed making an angle $θ^{\circ}$ in between them, number of images depends on $n = \frac{360^{\circ}}{θ^{\circ}}$ .

Thus, the number of images is inversely proportional to angle $θ$ between the mirrors.
Hence the number of images will decrease.

Two plane mirrors are placed making an angle θ∘ in between them. For an object placed in between the mirrors, if angle is gradually increased from 0∘ to 180∘, how will the number of images change: increase, decrease or remain unchanged?

Two plane mirrors are placed making an angle θ∘ in between them, number of images depends on n=360∘θ∘. Thus, the number of images is inversely proportional to angle θ between the mirrors. Hence the number of images will decrease.
