When a compound absorbs light one must think of the mechanism by which the compound absorbs the light. Light is composed of photons. Photons are specific quantums of energy. We measure light by a range of nanometers that correspond with specific color regions of the electromagnetic spectrum. The UV region is 280 to 400 nanometers. Most hetero cyclic compounds absorb radiation in both the UV-A and UV-B regions, particularly in the range of 280 to 350 nanometers, and are highly resistant to photodegradation. The range of photoexcitation (the nm range a molecule absorbs) is associated with both its bond stability and electron configuration.
What else can I help you with?
What are the colored chemical compounds in plants that absorb light?
The colored chemical compounds in plants that absorb light are called pigments. The main pigments responsible for absorbing light in plants are chlorophyll (green), carotenoids (orange and yellow), and anthocyanins (red, purple, and blue). These pigments play a crucial role in photosynthesis, the process by which plants convert light energy into chemical energy.
What compounds do many algae have to help them absorb light at different wavelenghts?
Many algae contain pigments such as chlorophyll a, chlorophyll b, carotenoids, and phycobilins to absorb light at different wavelengths. These compounds allow algae to capture light energy for photosynthesis efficiently across a broad spectrum of light wavelengths in the aquatic environment.
What is colored chemical compounds that absorbs light is?
Colored chemical compounds that absorb light are called pigments. Pigments selectively absorb certain wavelengths of light and reflect or transmit others, giving them their characteristic color. Common examples of pigments include chlorophyll in plants, hemoglobin in blood, and melanin in skin.
Is the light dependant reaction cyclic?
Yes, the light-dependent reaction of photosynthesis involves a cyclic flow of electrons between photosystem I and photosystem II. This cycle helps generate ATP and NADPH for the Calvin Cycle to produce glucose.
What is a colored chemical compounds that absorb light?
A colored chemical compound that absorbs light is known as a pigment. Pigments can selectively absorb certain wavelengths of light, giving them their characteristic color. This absorption of light by pigments plays a key role in various biological processes, such as photosynthesis in plants.

How is light reaction of photosynthesis started?
Absorbtion of light by photosystems in cyclic and non-cyclic photophosphorylation.
What are the colored chemical compounds in plants that absorb light?

Organic compounds must exhibit what property in order to be visualized by UV light?
They must be aromatic or highly conjugated compounds.
What are colored compounds that capture light?
Colored compounds that capture light are known as pigments. These compounds absorb specific wavelengths of light and reflect or transmit others, resulting in the perception of color. Pigments are commonly used in paints, dyes, and inks to provide color to various materials.
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.
