How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.
What is meant by the absorption spectrum of a pigment?
The absorption spectrum of pigment is the molecules response to light. The color of the pigment depends on the wavelengths of light the do not absorb.
Which absorption spectrum is equivalent to a fingerprint of a substance?
the infrared spetra
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.
Does the Sun produce a continuous spectrum or an absorption spectrum?
The photosphere of the sun doesn't really produce a continuous spectrum; there are discontinuities corresponding to energy levels of various chemical elements, called spectral lines. Notably Helium was discovered in the absorption lines of the solar spectrum and only later discovered on Earth.
The graph represents the absorption spectrum of chlorophyll The graph indicates that the energy used in photosynthesis is most likely obtained from which regions of the spectrum?
orange red and violet blue
Why is there chlorophyll in photosynthesis?
Chlorophyll is necessary in photosynthesis, because: 1. it absorbs the light necessary for photosynthesis mostly the blue and red light but poorly in green light because of electromagnetic spectrm 2. gives the leaves it green color
What is the photosynthetic pigment in plants?
There are a four main photosynthetic pigments in green plants. Chlorophyll a, chlorophyll b, carotene and xanthophyll. These all absorb different areas of the spectrum therefore allowing the plant maximum absorption of light from the sun, and hence photosynthesise effectively.
why is grass and trees green?
Grass and trees appear green due to a pigment called chlorophyll. Chlorophyll is a molecule found in the chloroplasts of plant cells, and it plays a critical role in the process of photosynthesis. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen. Chlorophyll absorbs light energy, particularly in the blue and red parts of the electromagnetic spectrum, while reflecting or transmitting green light. This reflected green light is what our eyes perceive, making the plants appear green to us. The reason chlorophyll absorbs light most efficiently in the blue and red regions of the spectrum is because these wavelengths carry the right amount of energy to drive the chemical reactions of photosynthesis. The green light is not as effectively absorbed and is therefore reflected back to our eyes. It's worth noting that there are different types of chlorophyll, such as chlorophyll-a and chlorophyll-b, which have slightly different absorption properties. These variations in chlorophyll molecules can contribute to the different shades of green observed in various plants. In summary, grass and trees appear green because chlorophyll, the pigment responsible for photosynthesis, absorbs light energy in the blue and red regions of the spectrum and reflects green light back to our eyes.
What is the relation between the electromagnetic spectrum of solar radiation and the absorption spectrum of chlorophyll?
Solar radiation peaks in energy in the mid-yellow range. Chlorphyll's absorption also peaks in this range. It is a demonstration of the adaption of plants to optimizing their production efficiency.
Would a plant exposed to only yellow light grow well?
No, it shouldn't do. In the absorption spectrum for chlorophyll (overall), yellow light is very low. This shows that not much light and hence energy is absorbed by the plant and therefore, not as much photosynthesis can occur.
Can plants really go through photosynthesis as long as the spectrum part of the artificial light has wavelengths that the chlorophyll can grab?
yes

Is an absorption spectrum also called a bright line spectrum?
No, its an absorption spectrum
The absorption spectrum for chlorophyll reveals that it?
Chlorophylls absorb light most strongly in the red and violet portions of the spectrum. Green light is poorly absorbed so when white light (which contains the entire visible spectrum) shines on leaves, green rays are transmitted and reflected giving leaves their green color. The similarity of the action spectrum of photosynthesis and the absorption spectrum of chlorophyll tells us that chlorophylls are the most important pigments in the process.
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.
