What is the maximum wavelength of the visible spectrum so that 3 rd order spectrum can be obtained by a plane diffraction grating having 5654 lines/cm?
Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength. Work function W = hγ o = h C / λ 0 λ 0 = h C / W = 6.626 X 10 -34 X 3 X 10 8
