A helium-neon laser of wavelength 633 nm is used to calibrate a diffraction grating. When a screen is placed 1.71 m away from the diffraction grating illuminated by this laser, the first-order maximum falls 26.7 cm from the central zeroth-order maximum, Given the spacing between maxima, what must be the spacing between the slits (in um)?
