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.
How a star is similar to the sun if it has the same absorption lines in its spectrum that occur in the sun spectrum?
because they will have the same elements in the atmosphere...

Why would the absorption spectrum of each element have lines in the same places as in its emission spectrum?
The absorption spectrum of an element have lines in the same places as in its emission spectrum because each line in the emission spectrum corresponds to a specific transition of electrons between energy levels. When light is absorbed by the element, electrons move from lower energy levels to higher ones, creating the same lines in the absorption spectrum as the emission spectrum. The frequencies of light absorbed and emitted are the same for a specific element, resulting in matching lines.
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.
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.
Why are the absorption spectrum and the emission spectrum the same for the same?
The absorption spectrum and the emission spectrum of the same substance are essentially complementary because they both arise from the same electronic transitions between energy levels of atoms or molecules. When a substance absorbs light, it takes in specific wavelengths corresponding to the energy differences between these levels, creating an absorption spectrum. Conversely, when the substance emits light, it releases energy as electrons return to lower energy states, producing an emission spectrum that features the same wavelengths as those absorbed. Thus, the lines in both spectra correspond to the same energy transitions, making them identical in appearance but reversed in process.
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 red line shows the same action spectrum corrected for the unequal number of protons emitted across the visible spectrum?
The red line that represents the same action spectrum corrected for the unequal number of protons emitted across the visible spectrum is typically referred to as the "quantum yield" or "relative efficiency" curve. This curve accounts for variations in photon emission and absorption across different wavelengths, providing a more accurate representation of the overall effectiveness of a process, such as photosynthesis or photobiological reactions. By normalizing the action spectrum, it highlights how effectively light at various wavelengths can drive the desired biological response.
Figure 10.1 shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis Why are they different?
The absorption spectrum shows which wave lengths are absorbed in each individual type of chlorophyll. The action spectrum shows which wavelengths of light are most effective for photosynthesis.
