What else can I help you with?
Absorption of what type of electromagnetic radiation results in electronic transitions?
Absorption of ultraviolet (UV) or visible light results in electronic transitions in atoms or molecules. This energy causes electrons to move to higher energy levels, leading to the absorption of specific wavelengths of light by the substance.
Why can you not se visible light to look at molecules?
The wavelength of visible light is larger than molecules.
What is q band in absorption spectra?
The Q band in absorption spectra refers to the region where electronic transitions occur between closely spaced energy levels in molecules or complexes. It typically corresponds to longer wavelengths in the visible or near-infrared range, and is often associated with changes in the vibrational and rotational motion of the molecules. The intensity and shape of the Q band can provide information about the structure and electronic properties of the molecules.
Which parts of the Sun's radiation are responsible for heating Earth's surface?
The visible light and infrared radiation from the Sun are primarily responsible for heating Earth's surface. Visible light is absorbed by the Earth's surface, warming it up, while infrared radiation is absorbed by greenhouse gases in the atmosphere, trapping heat and contributing to the greenhouse effect.
Why can't you use visible light to see molecules?
Visible light cannot be used to see molecules because the wavelength of visible light is much larger than the size of molecules. This means that visible light cannot resolve the small details of molecules, making them invisible to the human eye.
What is the maximum absorbance for beta-carotene?
The maximum absorbance for beta-carotene is around 450-480 nm. This range corresponds to the absorption of light in the visible spectrum by beta-carotene molecules.
What is calorescence?
Calorescence is the absorption of infrared radiation and emission of visible light.
What is the main visible specialisation for absorption of substances that is visible in intestines cell?
Mitochondria because it's function is cellular respiration
What ion is responsible for the blue colour?
The ion responsible for the blue color in many compounds is usually copper(II) ion (Cu2+). Copper(II) compounds often appear blue due to the absorption of certain wavelengths of light in the visible spectrum associated with the ion's electronic structure.
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.
What Is The Absorption Spectrum Of boron?
The absorption spectrum of boron typically shows strong absorption in the ultraviolet region, with some absorption in the visible spectrum as well. Boron's absorption spectrum is characterized by a series of sharp peaks due to transitions between energy levels in its atomic structure.
What is highest absorption to lowest. Highest Light Absorption?
The highest absorption in the electromagnetic spectrum includes gamma rays, X-rays, and ultraviolet light. Next comes visible light, followed by infrared, microwaves, and radio waves with the lowest absorption.
