The only difference, between ultra violate light and visible light, is their frequencies, UV has higher frequency than visible and since wavelength x frequency = the speed of light (which is constant at 3x108 ms-1), therefore wavelength is higher in UV. UV light is also not visible, unlike visible light!
so, in summery the difference is frequency and wave length.

What is the advantage of using UV-Vis spectroscopy compared to a spectronic 20?
UV-Vis spectroscopy allows for a wider range of wavelengths to be analyzed compared to a Spectronic 20 which is limited in the wavelengths it can measure. Additionally, UV-Vis spectroscopy provides higher sensitivity and accuracy in quantifying absorption of light by a sample compared to a Spectronic 20. UV-Vis spectroscopy also offers more advanced data analysis capabilities.
What is quantum transition for the uv-vis absorption?
Quantum transition for the UV-VIS absorption refers to taking the electron transitions associated with visible and ultraviolet.
How can one interpret UV-Vis data effectively?
To interpret UV-Vis data effectively, one must analyze the absorption peaks and patterns in the spectrum. By comparing the data to known standards or reference spectra, one can identify the compounds present and their concentrations. Additionally, understanding the principles of UV-Vis spectroscopy and the effects of factors such as solvent and pH can aid in accurate interpretation of the data.

What are the differences between UV-Vis and IR spectroscopy techniques in terms of their applications and capabilities?
UV-Vis spectroscopy is used to analyze the absorption of ultraviolet and visible light by molecules, providing information on electronic transitions. It is commonly used for analyzing organic compounds and determining their concentration. In contrast, IR spectroscopy measures the absorption of infrared light, providing information on molecular vibrations. This technique is useful for identifying functional groups in organic compounds and determining molecular structure. Overall, UV-Vis spectroscopy is more sensitive to electronic transitions, while IR spectroscopy is more sensitive to molecular vibrations.
What is UV-Vis spectroscopy used for in scientific research and analysis?
UV-Vis spectroscopy is used in scientific research and analysis to measure the absorption of ultraviolet and visible light by molecules. This technique helps scientists identify and quantify substances, study chemical reactions, and determine the concentration of compounds in a sample.
What is the purpose of UV-Vis spectroscopy and how is it used in analyzing chemical compounds?
UV-Vis spectroscopy is used to measure the absorption of ultraviolet and visible light by chemical compounds. This technique helps identify compounds based on their unique absorption patterns, allowing scientists to analyze their structure and concentration. UV-Vis spectroscopy is commonly used in fields such as chemistry, biochemistry, and environmental science for various applications, including determining the purity of substances, monitoring chemical reactions, and studying molecular interactions.
What are the characteristic features of the UV-Vis spectrum of beta carotene?
The characteristic features of the UV-Vis spectrum of beta carotene include absorption peaks in the visible range, specifically around 450-500 nm, due to its conjugated double bond system. This results in a yellow-orange color appearance.
What are the key differences between UV-Vis and IR spectroscopy techniques and how do they each contribute to the analysis of chemical compounds?
UV-Vis spectroscopy measures the absorption of ultraviolet and visible light by a compound, providing information on electronic transitions. IR spectroscopy measures the absorption of infrared light by a compound, providing information on molecular vibrations. UV-Vis is useful for analyzing conjugated systems and determining the presence of certain functional groups, while IR is useful for identifying specific functional groups and determining molecular structure. Both techniques are valuable for characterizing chemical compounds and can be used together for a more comprehensive analysis.
What is UV-VIS-IR transmission spectra?
It is a spectra that shows how transparent a material can be. in scientific terms, it is incidence of electromagnetic radiation (from the UV, Visible, Infrared wavelength regions) from a source to a material, and there is a detector which records the amount of radiation remaining after the transmission (these radiation that is gone is either reflected of the surface or absorbed by the material). The equipment that measures this is called UV-Vis-NIR spectrometer.
