Adiffraction grating contains 15,000 lines/inch. we pass a laser beam through the grating. the wavelength of the laser is 633 nm. on a screen 2.66m away, we observe spots of light. (a) how far (m) from the central maximum (m = 0) is the first-order maximum (m = 1) observed? (b) how far (m) from the central maximum (m = 0) is the second-order maximum (m = 2) observed? do not calculate this using the
