WebThe table below shows some of the characteristic absorption and emission lines of each star. You may not know where all of these elements have their emission lines. The chart below lists some of the more common ones and their approximate location in the electromagnetic spectrum. WebWhen white light passes through or is reflected by a colored substance, a characteristic portion of the mixed wavelengths is absorbed. The remaining light will then assume the complementary color to the wavelength (s) absorbed. This relationship is demonstrated by the color wheel shown on the right.
