Question

2) Two plane mirrors are arranged such that the angle between them is 40°. Calculate the no ofimages formed in this combination of mirrors.​

Answer 1

Answer:

360/40=9 ,so images =9-1=8

Explanation:

Answer 2

Answer:

9

EXPLANATION: the formula to find the number of images are 360/θ , where θ is the angle between the mirrors.

if the value of 360/θ is even number then the formula is 360/θ - 1,

if the value of 360/θ is odd number then the formula is 360/θ.

Here we have θ = 40°, then the number of the images formed by the mirrors are = 360/40 = 9, which is a odd number. Thus, the answer is 9.
