Question

image will formed when angle between two plane mirror is 30 degree​

Answer 1

Answer:

The number of images formed when two mirrors are placed at an angle theta to each other is given by:

n = ( 360 / theta ) - 1

So, here, we have the mirrors placed perpendicular to each other. So, theta = 90 degree

=> n = no. of images formed

=> n = ( 360 / 30 ) - 1

=> n = 12 - 1=> n = 11

So, a total of eleven images will be formedYou can also try for different angles.

Similarly, when the 2 mirrors are placed parallel to each other, theta = 0 degree

So, number of images formed = infinite

Also, when the two mirrors are placed side by side, theta = 180 degree

=> n = ( 360 / 180 ) - 1

=> n= 2 - 1

=> n = 1

And hence, only one image is formed as a whole.
