How many images of an object will be formed when the object is placed between two plane mirrors which are inclined at the following angles to one another?
(a) 120°
(b) 45°
(c) 180°
(d) 60°
(e) 90°
Answers
Explanation:
The formula to find no of images formed= Let the angle of inclination be n therefore. no of images =(360/n)-1. Hope it helps you please mark as brainliest.
Number of images:
(a) 120° = 2 images
(b) 45° = 7 images
(c) 180° = 1 images
(d) 60° = 5 images
(e) 90° = 3 images
Explanation:
The number of images formed between two plane mirror are given by the formula:
n = 360°/θ - 1
Where, θ = Angle between mirrors
(a) n = 360°/120° - 1 = 3 - 1 = 2 images
(b) n = 360°/45° - 1 = 8 - 1 = 7 images
(c) n = 360°/180° - 1 = 2 - 1 = 1 images
(d) n = 360°/60° - 1 = 6 - 1 = 5 images
(e) n = 360°/90° - 1 = 4 - 1 = 3 images
Number of images increases with decrease in angle between the mirrors as the image formed in one mirror becomes object for the another mirror.
