all chemicals that can been seen by the naked eye absorb certain wavelengths of light of the visible light spectrum. it is the light that is absorbed that is what is seen. if a substance (or chemical) were to reflect all wavelengths of light (in the visible spectrum), it would be invisible.
The pigments that absorb light energy in the eye are mainly found in the rods and cones of the retina. Rods are responsible for vision in low light conditions while cones are responsible for color vision.
Pigments such as chlorophyll are used to capture light in photosynthesis. These pigments absorb light energy and convert it into chemical energy, which is used to drive the process of photosynthesis in plants.
When two or more substances combine, they create one or more new substances, which sometimes have different molecular structures from the original substances, meaning they absorb and radiate light in different ways, leading to a color change.
Luminous materials are substances or objects that emit light on their own without needing an external light source. This could include materials like glow-in-the-dark paint or phosphorescent stickers that absorb light energy and then release it slowly over time. These materials are commonly used for safety, decoration, and entertainment purposes.
Not quite. Remember that electrons are part particles and part waves. Light is given off when an electron drops from one energy state to a lower one. In answer to a different question, and may be the one you ask, When light strikes a phosphor, the electrons in the phosphor absorb energy, and give it off some time later. This is Phosphorescence.
Yes, they do absorb light. They transfer the light-energy to chemical energy by a proces called fotosynthesis.
Substances that absorb light convert it to various forms of energy, such as heat or electrical energy. This process is known as photovoltaic effect and is utilized in solar panels to generate electricity from sunlight.
Substances that absorb light can convert it into different forms of energy, depending on their properties. For instance, photosynthetic pigments in plants convert light energy into chemical energy through the process of photosynthesis. In solar panels, light-absorbing materials convert light energy into electrical energy through the photovoltaic effect.

Optically active
It is called fluorescence or phosphorescence. This phenomenon occurs when a substance absorbs energy in the form of light or other electromagnetic radiation and then emits light at a different wavelength.
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.
When substances that absorb light convert it, they typically transform the light energy into heat energy. This process involves the absorption of photons, which excites electrons within the substance, leading to increased molecular vibrations that result in heat. Additionally, some materials may convert light energy into chemical energy through processes like photosynthesis.
Substances that absorb light can be converted to higher energy states, leading to excitation or even a chemical reaction. This absorption of light can lead to various phenomena like fluorescence, phosphorescence, or photochemical reactions, depending on the specific molecule and conditions.
Bacteria that can absorb light energy and convert it into ATP are commonly called phototrophic bacteria. They use light as an energy source for photosynthesis, similar to plants.
Chlorophyll a and chlorophyll b are the main molecules in chloroplasts that can absorb light for photosynthesis. These pigments absorb light energy and convert it into chemical energy, which is used to drive the process of photosynthesis.
UV light is invisible to the human eye, which is why it is sometimes referred to as 'black light'. However, some materials (e.g. DayGlo) can absorb UV energy and convert it into visible light energy. They are said to be fluorescent.
