WebFrom tan A, use your calculator to find the angle A, and from this find sin A. Use the formula d sin A = wavelength to calculate the wavelength of green light. You will need the value of d, spacing, i.e. distance from one ruling to the next. If the grating has 300 lines / mm then the spacing is 1 / 300,000m. Web15 nov. 2010 · If you have a single source, the best way to measure the wavelength is using interference. If you've got an easy way to see the light, you can just sent it through a diffraction grating of known spacing, and measure the spacing between the bright spots. Or, if you want to be more precise, you can use a Michelson interferometer (which is what's ...
