Question

2. How many images of a candle will be formed when the angle between the 2 mirrors is
45°?​

Answer 1

Answer:

here's yr ans

Explanation:

The formula for number of images formed by two plane mirrors placed at certain angle is (360/n).[where n=angle between the mirrors]

The most important thing to remember is that, every time the number of images formed are only ODD numbers. (for the reason of odd number formation, refer textbooks like hc verma)

if the result is even then you need to subtract 1 from that.

if it is odd u need not subtract , since the number of images ever formed are only odd.

so for the angle 45 degrees the number of images formed are:

360/45

=8

in this case, since the images formed are even u need to subtract 1 from it i.e

8–1

=7

so the number of images formed are 7.

now lets take other example==>

if the angle between the mirrors is120 degrees he no of images formed=?

360/n= 360/120

=3

so images formed are 3.
