Question

What are the precautions that should be taken care of while drawing ray diagrams while two mirrors are placed parallel to each other and in the second case they are placed perpendicular to each other....??

Answer 1

For precaution in two parallel mirror never draw ray at 90 degree to any mirror surface.


Means keep angle of incident greater than 0 degree.



For two mirror at 90 degree

draw Ray at both mirror at 0 angle of incidence from object. Means at 90 degree on the surface of mirror.



Only these precautions is necessary.





Thanks for asking.
