Explain the difference between emission spectrum and absorption spectrum?
Answers
emission spectrum :
When energy is absorbed by electrons of an atom, electrons move from lower energy levels to higher energy levels. These excited electrons have to radiate energy to return to ground states from the excited state, which is unstable. The emission spectrum is formed by the frequencies of these emitted light.
- Comprise coloured lines in the spectrum.
- It is helpful in figuring out the composition of a certain matter .
- The type of photons emitted is helpful in figuring out the kind of elements the substance is made of as each element radiates a different amount of energy and has a unique emission level.
absorption spectrum is constituted by the frequencies of light transmitted with dark bands when energy is absorbed by the electrons in the ground state to reach higher energy states.
- Comprise dark lines or gaps in the spectrum.
- Can be used to figure out the ability of certain objects to retain heat and its absorption level.
- The wavelengths of light absorbed is helpful in figuring out the number of substances in the sample a tabular column.
The main difference between emission and absorption spectra is that an emission spectrum has different coloured lines in the spectrum, whereas an absorption spectrum has dark-coloured lines in the spectrum.
