What is the dissimilarity between these wavelengths

Reference no: EM13674043

Visible light passes through a diffraction grating that has 900 slits per centimetre, and the interference pattern is observed on a screen that is 2.58m from the grating. In the first-order spectrum, maxima for two dissimilar wavelengths are separated on the screen by 3.18mm. What is the dissimilarity between these wavelengths?
