Question

the angle between two mirror is 72 degree find the number of image formed between the mirror

Answer 1

no of images = ( angle between the mirrors /360 ) -1
                      = 72/360 - 1
                      = 5 -1
                      = 4 

Therefore the number of images formed is 4

Hope it helps!!

Answer 2

Given:

The angle between the two mirrors is 72 degrees.

To Find:

The number of images formed in the mirror.

Solution:

To find the number of images formed between the mirror we will follow the following steps:

As we know,

The formula for finding the number of images formed between the two mirrors is:

$n \: = \frac{360 \: }{angle \: between \: two \: mirrors} - 1$

Here, n is the number of images formed between the two mirrors.

The angle between two mirrors = 72°.

Now, putting the value of n in the above formula we get,

$n \: = \frac{360}{72} - 1$

$n \: = 5 - 1 = 4$

Henceforth, the number of images formed in the mirror is 4.
