The light which has one wavelength or a mixture of two or more wavelengths should be analyzed in some copper-containing substances that emit green light when they are heated in a flame. Concept Introduction: The electrons are excited thermally when the light is used by an object. As a result, an emission spectrum comes. The emission spectrum of a substance is seen by energizing a sample of material with either thermal energy or some other form of energy (such as a high-voltage electrical discharge if the substance is a gas). A “red-hot” or “white-hot” iron bar freshly removed from a fire produces a characteristic glow. The glow is the visible portion of its emission spectrum. The heat given off by the same iron bar is another portion of its emission spectrum called the infrared region. A feature common to the emission spectrum of the sun and that of a heated solid is that both are continuous. Hence, all wavelengths of visible light are present in each spectrum.
