The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm (red) and 486 nm blue). Light from a hydrogen lamp illuminates a diffraction grating with 500 lines per mm, and the light is observed on a screen 1.50 m behind the grating.
What is the distance between the first-order red and blue fringes?
I need to see the equations and what you plugged in so I can understand how to do the problem...I am not sure which equation to use.
