What is produced when light from a hot solid passes through a cooler gas?
When light from a hot solid passes through a cooler gas, absorption lines are produced in the spectrum. The cooler gas absorbs certain wavelengths of the light, creating dark lines in the spectrum where those wavelengths are missing. This phenomenon is known as absorption spectroscopy.
What are some comparisons with a absorption spectrum and a continuous spectrum?
An absorption spectrum shows dark lines at specific wavelengths where light has been absorbed by a substance. A continuous spectrum shows all colors/wavelengths with no gaps, like the rainbow. The main difference is that the absorption spectrum has specific dark lines while the continuous spectrum is smooth and uninterrupted.
What is the absorption spectrum of a given wavelength of light?
The absorption spectrum shows the wavelengths of light that are absorbed by a substance. Each substance has a unique absorption spectrum due to its molecular structure and composition. The absorption spectrum is determined by measuring the amount of light absorbed at different wavelengths.
Which of the three types of spectrum would be observed?
The type of spectrum observed would depend on the source of light. A continuous spectrum is produced by a hot, dense object like a solid, liquid, or dense gas. An emission spectrum is generated by a thin, hot gas, while an absorption spectrum is created by a cooler gas in front of a light source.
Why doesn't the action spectrum for photosynthesis exactly match the absorption spectrum of chlorophyll a?
The action spectrum for photosynthesis doesn't exactly match the absorption spectrum of chlorophyll a because other pigments, like chlorophyll b and carotenoids, also play a role in capturing light energy for photosynthesis. These additional pigments have absorption peaks at different wavelengths, contributing to the overall light absorption by the plant. As a result, the combined absorption spectra of all pigments involved in photosynthesis do not perfectly align with the action spectrum.
Is an absorption spectrum also called a bright line spectrum?
No, an absorption spectrum and a bright line spectrum are not the same. An absorption spectrum is produced when light is absorbed by atoms or molecules, showing dark lines at specific wavelengths. On the other hand, a bright line spectrum is produced when atoms or molecules emit light at specific wavelengths, creating bright lines in the spectrum.
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
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 meant by an absorption spectrum?
In the absorption spectrum the peaks are due to preferential absorption at a definite wavelength by molecules, ions, etc.
What are the absorption lines in the infrared portion of the spectrum of a star that are produced by hyrdrogen are from?
The absorption lines in the infrared portion of the spectrum of a star produced by hydrogen are primarily the Paschen series. These lines are transitions of electrons in hydrogen atoms from higher energy levels to the third energy level (n=3). Typical Paschen series lines in the infrared include Paschen-alpha at 1.875 μm and Paschen-beta at 1.282 μm.
How are absorption and emission lines produced in a stellar spectrum What information might absorption lines in the spectrum of a star reveal about a cloud of cool gas lying between us and the star?
Absorption lines are produced when elements in the outer layers of a star absorb specific wavelengths of light, leading to dark lines in the spectrum. These lines indicate the presence of certain chemical elements in the star's atmosphere. Absorption lines from a cool gas cloud between a star and Earth can reveal the composition, density, and temperature of the cloud, providing valuable information about the interstellar medium.

How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
The number of lines in the emission spectrum is the same as in the absorption spectrum for a given element. The difference lies in the intensity of these lines; in emission, they represent light being emitted, while in absorption, they represent light being absorbed.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
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.
