Question

HEYA ¡!

when an object is kept between two plane mirrors making certain angle face images of form what is the measure of angle between the plane mirror

plz answer

Answer 1

There is a formula for such questions.

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.
