Question

A composite light source is directed at a diffraction grating with a grating constant of 267 lines/mm. The diffraction pattern is viewed on a screen that is 1.19 m from the grating. If a 3rd order maxima is loacted at a distance of 0.484 m from the central maxima, what is the wavelangth of the associated light. Measure this wavelength in nanometers.

Step 1

Given grating constant = 267 lines/mm = 267 x 10^3 lines/m Spacing = 1 / grating constant = 1 / 267 x 10^3 = 3.754 x 10^-6 m Show more…
