physics waves question
difference between modal dispersion and multipath dispersion?
also on question 4c
i wrote to prevent modal dispersion so that the ray along the axis does not travel a shorter distance per metre of fibre than the ray that continually undergoes TIR, it wouldn't emerge with the next pulse.
