Calculate the difference between these wavelengths

Reference no: EM13525462

Visible light passes through a diffraction grating that has 900 slits per centimeter, and the interference pattern is observed on a screen that is 2.42 from the grating.

In the first-order spectrum, maxima for two different wavelengths are separated on the screen by 2.70mm. What is the difference between these wavelengths?
