Question

calculate the number of images formed by two plane mirrors is angle between them is 1)30 degree
2)60 degree
3)90 degree
4)0 degree

Answer 1

Answer:

No of images = 360/Φ - 1

Explanation:

1) 360/30 - 1 = 11

2) 360/60 -1 = 5

3) 360 / 90 - 1 = 3

4) 360 / 0 - 1 = infinity (no image will form)
