Question

If two Mirrors are placed at an angle of 120 degree, how many images will be formed? ​​

Answer 1

$\huge \pink{a} \blue{n} \red{s} \green{w} \orange{e} r$

when a person places an object between two plane mirrors kept at an angle of 120 degrees the no. of images are formed are 2 images. because when we are finding the no. of images formed in between two plane mirrors when kept at an angle the formula to find no. of images formed is

360 degrees / theta - 1

in above the object is kept between two plane mirrors kept at an angle 120 degrees. now to find the no. of images formed is

360 degrees / theta - 1

360 degrees / 120 degrees - 1

=> 3 - 1

=> 2

2 images are formed
