Visible light passes through a diffraction grating that has 900 slits per centimeter, and the interference pattern is observed on a screen that is 2.78 m from the grating. In the first-order spectrum, maxima for two different wavelengths are separated on the screen by 3.02 mm. What is the difference between these wavelengths?
