Question

two plane mirrors are lying perpendicular to each other there is a lamp in between Mirrors the number of images of lamp will be ​

Answer 1

Answer:

Let, the angle is x

If the value of 360/x is even, then we will use the formula

no. of images= 360/x -1

If the value of 360/x is odd, then we use the formula

no. of images= 360/x

Now, in this question, let us first find value 360/x

so, 360/90 = 4 , where 4 is an even number.

so we will use the formula 360/x - 1

so, 360/90 -1 =4–1 = 3

so the image formed will be three.
