The numerical aperture (NA) of a fiber characterizes the ability of a fiber to collect light (a high NA means it collects more light). The NA is defined as the sine of the maximum external angle of a ray entering the fiber that can be trapped by total internal 1/2 reflection. Show that NA = n, sine, =(n° – n²)"
