What causes electromagnetic radiation to change its wavelengths?
Absorption and re-emission.
What type of organic compounds show UV absorption bands?
Aromatic compounds, conjugated dienes, and compounds with extensive pi-electron systems often show UV absorption bands. These compounds have delocalized electrons that can undergo electronic transitions when exposed to ultraviolet light, leading to absorption of UV radiation.
Why you get broad peak in UV spectroscopy instead of sharp peak?
UV-visible absorption spectroscopy probes electronic transitions due to electronic excited states, where as absorption of IR radiation excites molecular vibrations and no electronic excited states. However, UV-visible radiation can also excite the molecular vibrations as well, and so what is observed is the superposition of the electronic absorption in addition to the vibrational absorption spectra. IR spectra are broadened by molecular rotations, which are caused by the absorption of lower energy microwave radiation (and rotational spectra can be extremely sharp). If the species you are probing are atoms only, than they do not have any vibrations (because there are no bonds) and so the UV-visible spectra of atoms is very sharp.
What do telescopes do with electromagnetic radiation?
Telescopes focus electromagnetic radiation for closer observation.
How is visible light and electromagnetic radiation different?
They are not different.Visible light IS electromagnetic radiation.
What is the wavelength of the water?
Water absorbs over a wide range of electromagnetic radiation with rotational transitions and intermolecular vibrations responsible for absorption in the microwave (≈ 1 mm - 10 cm wavelength) and far-infrared (≈ 10 µm - 1 mm), intramolecular vibrational transitions in the infrared (≈ 1 µ- 10 µ) and electronic . 1.lsbu.ac.uk/water/water_vibrational_spectrum.html
What frequency of electromagnetic radiation corresponds to vibrational transitions?
microwave
What is water absorption?
The absorption of electromagnetic radiation by water depends on the state of the water.
What is an absorption line?
An absorption line is a line which corresponds to the absorption of electromagnetic radiation at a specific wavelength.
What causes electromagnetic radiation to change its wavelengths?
Absorption and re-emission.
What is wave absorption?
Wave Absorption is electromagnetic radiation a.k.a the electrons of an atom. I hope this helped!! XD
What is an absorption coefficient?
An absorption coefficient is a measure of the absorption of electromagnetic radiation as it passes through a specific substance - calculated as the fraction of incident radiation absorbed by unit mass or unit thickness.
Electromagnetic waves with higher have higher energies?
Both energies as well as rotational energy are quantized. Electronic energy transitions are associated with short wave radiation, vibrational energy transitions - infrared region and rotational energy with the microwave region
What is the transfer of of energy carried by light waves to particles in matter?
This process is called energy absorption.
Is gravity caused by the absorption of electromagnetic emission?
No. Gravity is a characteristic property of space and mass that exists whether or not there is any electromagnetic radiation in the neighborhood. Its cause is unknown.
