What does a dark line in a spectrum mean?
A dark line in a spectrum, also known as an absorption line, represents a specific wavelength of light that has been absorbed by a substance between the source of light and the observer. The presence of dark lines in a spectrum can provide information about the composition and properties of the absorbing material.
What were dark lines in the spectrum named for?
Dark lines in the spectrum were named after German physicist Joseph von Fraunhofer, who first systematically studied them. They are commonly known as Fraunhofer lines and are formed when certain chemical elements absorb specific wavelengths of light, creating dark bands in the spectrum.
Why dark line appears in absorption spectrum?
Dark lines in an absorption spectrum are caused by material existing between the source of light and the observation point. This material can absorb light from the source at specific energies corresponding to the excitation energies of the molecules, atoms, or ions making up the material.
What is the color of mercury spectrum line of wavelength 576.96 nanometet?
The color of a mercury spectrum line with a wavelength of 576.96 nanometers is green.
What is the difference between a continuous spectrum an a line spectrum?
A continuous spectrum contains an unbroken range of wavelengths, such as the colors of a rainbow. A line spectrum consists of discrete, individual lines at specific wavelengths, typically seen when elements emit light at specific energies.
