What does the absorption spectrum show us or tell us?
The absorption spectrum shows the specific wavelengths of light that are absorbed by a material, indicating the energy levels of electrons in the substance. By analyzing the absorption spectrum, scientists can identify the chemical composition of the material and understand its electronic structure.
How many absorption bands are in uv spectrum for azo polyamides?
Azo polyamides typically exhibit absorption bands in the UV spectrum due to the presence of azo groups. The exact number of absorption bands can vary depending on the specific chemical structure of the polymer and the environment. Typically, azo polyamides show absorption bands in the range of 300-400 nm.
Dark lines in an absorption spectrum are called?
Dark lines in an absorption spectrum are called absorption lines. These lines correspond to wavelengths of light that have been absorbed by specific elements or molecules in the sample being analyzed. They appear as dips or gaps in the spectrum where less light is detected.
What is a band spectrum?
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
The absorption spectrum of a hydrogen atom contains dark bands at specific wavelengths The emission spectrum of a hydrogen atom contains bright bands at the same wavelengths Explain what causes ther?
The dark bands in the absorption spectrum occur when electrons in the hydrogen atom absorb energy and move to higher energy levels. The bright bands in the emission spectrum appear when these excited electrons drop back down to lower energy levels and release energy in the form of light at specific wavelengths, which correspond to the energy differences between the energy levels.
