Question

(C) Write formula to calculate the number of images formed when two plane mirrors are used in
combination. Also find the number of images formed if two mirrors are placed perpendicular to
each other.​

Answer 1

Answer:

So, 360∘40∘= 9, where 9 is an odd number. Thus, the images formed will be 9. So, 360∘90∘= 4, where 4 is an even number. Thus, the images formed will be 3.

...

1. n = 9. b) θ = 60∘

2. n = 3. c) θ = 60∘

3. n = 5. d) θ = 60∘

4. n = 7.

5. n = 1.
