No.of images between two plane inclined mirrors is given by the formula (n)
n = 360/angle of incidence - 1
So , here n = 5
Therefore,
5 = 360° / angle of incidence - 1
360°/ angle of incidence = 6
Angle of incidence = 360°/6 = 60°
n = 360/angle of incidence - 1
So , here n = 5
Therefore,
5 = 360° / angle of incidence - 1
360°/ angle of incidence = 6
Angle of incidence = 360°/6 = 60°
