    How to calculate the frequency given a colour, angle, 100 slits/mm.

    So for my assignment I have to calculate the wavelength given an angle, colour, 100 slits/mm diffraction rating but no frequency. Angle = 3.4 degrees Colour = Purple For v =∫λ, I need the wavelength or frequency to work out anything, v is the speed of light. But I cannot see how to find this...
