What wavelengths of electromagnetic radiation will follow a fiber optic cable?
Seems like common fiber optic cables work with light in the visible or IR spectrum (450-1500 nanometers). But do higher and lower energies also follow the path of a fiber optic cable? How high of an energy can you transmit before the energy just goes in a straight line and exits a fiber optic cable where it bends?
