Diffraction GratingA diffraction grating is the tool of choice for separating the colors in incident light.
This calculation is designed to allow you to enter data and then click on the quantity you wish to calculate in the active formula above. The data will not be forced to be consistent until you click on a quantity to calculate. Default values will be entered for unspecified parameters, but all values may be changed. Note: The small angle approximation was not used in the calculations above, but it may be sufficiently accurate for laboratory calculations.
