Calculate what is the wavelength of the laser light

Reference no: EM13558613

Light from an argon laser strikes a diffraction grating that has 5340 lines/cm. The central and first order principal maxima are separated by 0.488 m on a wall 1.74 m from the grating. Determine the wavelength of the laser light. (Assume that the light is incident normally on the gratings.)
