A beam of light consisting of wavelengths from 455 nm to 630 nm is directed perpendicularly onto a diffraction grating with 155 lines/mm. (a) What is the lowest order that is overlapped by another order? (b) What is the highest order for which the complete wavelength range of the beam is present? In that highest order, at what angle does the light at wavelength (c) 455 nm and (d) 630 nm appear? (e) What is the greatest angle at which the light at wavelength 455 nm appears?
