Match the number of images formed by two plane mirrors with the corresponding angle between them.
The correct option is
When two plane mirrors are placed at some angle, multiple images of an object are formed.
The number of images formed is given by the formula N =(360θ)−1; where θ is the angle between the plane mirrors in degrees. Therefore, when
for θ=60, N=(36060)−1=5for θ=120,N=(360120)−1=2for θ=90, N=(36090)−1=3for θ=180,N=(360180)−1=1
