Dictionary.com defines a bright line spectrum as "the spectrum of an incandescent substance appearing on a spectrogram as one or more bright lines against a dark background." Heating a material in its gaseous state causes it to give off light that creates bright lines of different colors when they pass through a prism, according to About.com.Continue Reading
When white light from the sun passes through a prism, it creates the full rainbow of colors. However, the University of Colorado indicates that the heated gases give off light in specific wavelengths that are responsible for the bright line spectra. Each material gives off a spectrum so unique in nature, it allows the scientist to identify the gas he is heating through the science of spectroscopy. In addition to the lines in the visible spectrum, the gases also create lines that are invisible to the human eye but detectable using other devices.
About.com says that as electrons change from one atomic orbital to the next, their energy changes. Changing from an orbital at a higher energy level to a lower one gives off this energy in the form of a photon of energy, which creates the light for the spectra. Since each element has a unique set of electrons in its orbitals, each spectrum is unique.Learn more about Colors
A rainbow is caused by the sun hitting water droplets in the atmosphere and reflecting the light so that people see a spectrum of colors. Rainbows are bowed in the center due to the fact that rainbows result from a group of circular arcs that have one common center.Full Answer >
The hottest flame is violet on the color spectrum and white in the visible spectrum. The type of fuel and impurities, in addition to the flame temperature, contribute to the color of the flame.Full Answer >
A laser beam is a strong, thin, monochromatic, directional ray of electromagnetic energy or radiation inside the visible light spectrum. A laser machine energizes the particles in a laser path, causing movement of the electrons of these particles to a higher orbit; this releases photons and produces a laser beam.Full Answer >
Black is the color that absorbs the most heat among all the colors in the spectrum. Black objects absorb all wavelengths of light and reflect none of them. Absorbed light is converted to heat.Full Answer >
