WebDiffraction and Interference. We know that visible light is the type of electromagnetic wave to which our eyes responds. As we have seen previously, light obeys the equation. c = f λ, where c = 3.00 × 10 8 m/s is the speed of light in vacuum, f is the frequency of the electromagnetic wave in Hz (or s –1 ), and λ is its wavelength in m. WebDiffraction gratings allow optical spectroscopy. A grating is a set of equally spaced, narrow, parallel sources. A grating disperses light of different wavelengths to give, for …
