Chlorophyll and carotenoids are examples of molecules that absorb specific wavelengths of light for photosynthesis in plants. In the field of medicine, hemoglobin and melanin are molecules that absorb specific wavelengths of light for various diagnostic and therapeutic purposes.
What else can I help you with?
Why do you see objects as different colors when light is shining on them?
Objects appear to have different colors when light shines on them because they selectively absorb and reflect certain wavelengths of light. The absorbed light energy excites the object's molecules, causing them to emit specific wavelengths of light that we perceive as color. The colors we see are determined by the wavelengths of light that are reflected back to our eyes.
What materials absorb light and how do they affect the absorption process?
Materials that absorb light typically contain pigments or dyes that are able to absorb specific wavelengths of light. When light hits these materials, the pigments or dyes absorb the light energy, causing the electrons in the molecules to become excited. This absorption process results in the conversion of light energy into heat or other forms of energy, depending on the material.
How can light be absorb?
Light can be absorbed when its energy is transferred to the atoms or molecules of a material, causing them to transition to a higher energy state. This absorption can result in heating of the material or cause chemical reactions to occur. Different materials have specific wavelengths of light that they can absorb based on the energy levels of their electrons.
Why a color paddle decreases the intensity of the light passing through it?
A color paddle reduces light intensity by selectively absorbing certain wavelengths of light based on its color. The molecules in the pigment of the paddle absorb specific wavelengths, which decreases the overall intensity of light passing through because some of the light energy is converted to heat.
What are the substances in plastids that absorb various wavelengths of light?
Chlorophylls, carotenoids, and phycobilins are the substances in plastids that absorb various wavelengths of light for photosynthesis. Each pigment absorbs different wavelengths of light to maximize the capture of energy for photosynthesis.
What are colored molecules that absorb light?
Colored molecules that absorb light are usually organic compounds that contain conjugated double bonds or transition metal ions in their structure. These molecules absorb specific wavelengths of light, causing them to appear colored. The absorption of light by these molecules leads to the excitation of electrons to higher energy levels.

The colors we see are determined by the wavelengths of light that are reflected back to our eyes.
What causes the dark bands observed in a solar spectrum?
The dark bands are caused from the differnet chemical elements which absorb light at specific wavelengths.
What materials absorb light and how do they affect the absorption process?
Materials that absorb light typically contain pigments or dyes that are able to absorb specific wavelengths of light. When light hits these materials, the pigments or dyes absorb the light energy, causing the electrons in the molecules to become excited. This absorption process results in the conversion of light energy into heat or other forms of energy, depending on the material.
Why are pigments such as anthocyanins coloured?
These pigments absorb specific wavelengths of visible light while scattering the remaining light.

Chlorophylls, carotenoids, and phycobilins are the substances in plastids that absorb various wavelengths of light for photosynthesis. Each pigment absorbs different wavelengths of light to maximize the capture of energy for photosynthesis.
What physical phenomenon is causing each dye to absorb light of one or more colors and transmit light of other colors?
In a spectrometer, each dye will absorb light of certain colors and transmit light of other colors because of the nature of the atoms of the object and the frequency of the light. If the frequency of the light is the same as the frequency that the electrons in the atoms are vibrating, then the light will be absorbed and transferred into vibrational motion.
How does colored glass transmit and absorb light?
Colored glass transmits and absorbs light based on its chemical composition. The atoms or molecules in the glass interact with the light, selectively absorbing certain wavelengths while allowing others to pass through. This absorption and transmission of specific wavelengths give the glass its characteristic color.
Cone cells are color photoreceptors that use different retinal molecules to absorb different wavelengths of light?
While cone cells are the color photoreceptors in the eye, they use different opsin molecules for the absorption of different wavelengths of light. So the answer would be false.
What absorb wavelenghts of light?
Different substances absorb different wavelengths of light based on their molecular structure. For example, chlorophyll absorbs mainly blue and red light, while pigments like carotenoids absorb blue and green light. This absorption of specific wavelengths allows substances to either reflect or transmit the remaining light we see as their color.
