4. A monochromatic ligh goes normally through a grating of width of 2.25 cm and 10+ rulings. The first principal maximum appears at 0=11.5, and the 4th principal maximum is missing. (a) Find the minimum width of a single slit on the grating. (b) Find the wavelength of the light. (c) The work function of potassium is 2.29eV. Can this light cause photoelectric effect? If it can, find the maximal speed of free electrons. (1eV=1.6010-J) 4. A monochromatic ligh goes normally through a grating of width of 2.25 cm and 10+ rulings.
