Question

how many images will be formed if two Mirrors are kept at angle of 30 degree to each other​

Answer 1

$\frac{360}{30}-1 = 11$

11 images are formed.

$if \: \theta \: is \: the \: angle \: the \: number \: of \: images \: formed \: are \\ \\ \frac{360}{ \theta} \: for \: odd \: outcome \: and \: \: \frac{360}{ \theta} - 1 \: for \: even$

hope it helps

Answer 2

Answer:

11 images

Explanation:

Trick to find the number of images formed can be found by using a formula.

Formula is as follows:

$\dfrac{360^ \circ}{x^\circ} - 1$

Here, x° refers to angle  present between two mirrors.

According to the question, x = 30°. Substituting in the formula, we get,

$\implies \dfrac{360^\circ}{30^\circ} - 1\\\\\implies 12 - 1\\\\\implies 11$

Hence 11 images would be formed if two mirrors are placed at an angle of 30°.
