Although optical fibres do not break easily, is it possible to bend the optical fibre too much that light that travels within the optical fibre will strike the wall at less than the critical angle and thus escape from the fibre through the wall?
Pls enlighten me. Thanks!
(I came across this question in a test paper but i don't think it is makes sense cos i think the engineers who designed the optical fibres surely would have considered this issue.)
