Carbon Cycle and the Earth's Climate - Columbia University
Radiation can be emitted or absorbed by matter. When matter absorbs light or infrared radiation, the energy of that radiation is transformed to thermal motion of particles in the matter, or, for shorter wavelengths (ultraviolet, X-ray), the radiation’s energy is absorbed within the atoms or molecules and may possibly ionize them by knocking out an electron.
Space is filled with waves of various wavelengths. In addition to visible light, there are wavelengths that cannot be seen by the naked eye, such as radio waves and infrared, ultraviolet, X-, and gamma rays. These are collectively known as electromagnetic waves because they pass through space by alternately oscillating between electric and magnetic fields. Light is a type of electromagnetic wave. The electromagnetic waves reaching us consist of only a portion of the visible light, near-infrared rays and radio waves from space because the earth is surrounded by a layer of gases known as the atmosphere. This structure is intimately related to the existence of life on earth.

HPS lights typically provide limited nanometer wavelengths (color spectrums), while many LED grow lights offer only a few colors. Sunlight, by comparison, consists of numerous spectrums, including ultraviolet and infrared varieties that extend beyond the naked eye.
The positive effect of photobiostimulation on animal cells is analogous to photosynthesis in plant cells, whereby a chain of chemical reactions are set in motion.

This lab relies on an oddity of the light sensors used in digital cameras, which are either CCD or CMOS detectors. Both kinds are sensitive to visible light (which is why they are used), but are even more sensitive to infrared light near the visible spectrum (see graph). So, for a CCD or CMOS camera to match what a human sees, all of the infrared light (wavelengths longer than 700 nanometers) must be removed with a filter. Removing this filter (as in the web page ) restores the CCD/CMOS's sensitivity to infrared light.
. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen. (Boundary: Further details of the photosynthesis process are not taught at this grade level.)

The Discovery of the Spectrum of Light - Newton, …
The colors that we see are the visible part of the electromagneticspectrum of energy. Energy travels at 186,000 miles/second, and consistsof vertical and horizontal wavelengths. The shorter the wavelength, the greaterthe amount of energy. Exposure to any energy below the visible spectrum for anextended period of time is harmful, and can cause reactions from darkening ofthe skin and cataracts (ultraviolet light) to gene mutations and cancer todeath, depending upon the amount of exposure and the wavelength. Infrared wavesare felt as warmth, and are used in microwave ovens and radar. These wavelengthsmay also be harmful with extended exposure. Radio and TV waves are the longestwavelengths. Light can also be considered as particles (photons) of light.

Depending on a main sequence star's spectral type, even a planet with 's atmospheric composition may be colored differently. In general, larger and more massive, main-sequence ("dwarf") stars have hotter surface temperatures than our Sun, , and so they radiate more photons, particularly towards the more energetic, bluish end of the spectrum. As a result of their greater luminosity, Earth-like planets would orbit farther away from hotter dwarf stars to avoid getting scorched, but their skies would still appear bluish due to of abundant bluish photons. Around smaller, less massive and dimmer dwarf stars, however, planets would have to orbit closer in order to sustain a surface temperature that is warm enough to keep water liquid and so the star would appear larger in the sky. In addition, stars with surface temperatures of 3,300 kelvins or lower (red dwarfs of spectral type M2.5 such as , or redder) would emit so fewer photons towards the bluish wavelengths compared to Sol that the sky would appear whitish down to reddish to Human eyes (more from ). If comparatively more bluish or reddish light reaches a planet's surface than on Earth, photosynthetic plant-type life may may not be greenish in color, because such life will have evolved to different pigments in order to optimize their use of available and so color the appearance of the planet's land surfaces accordingly.

Extraterrestrial photosynthetic plant-type life may look quite look different in color because they will have evolved their own pigments based on the colors of light reaching their surfaces. of NASA's Goddard Institute for Space Sciences has modelled the light reaching the surfaces of Earth-sized worlds orbiting their host stars at distances hospitable to Earth-type life, where liquid water could exist on a planetary surface, where depending on the star's brightness (and color) and the planet's atmosphere. Kiang found that "plants" on Earth-like planets orbiting stars somewhat brighter and bluer than the Sun might look yellow or orange, and even look bluish by reflecting a dangerous overabundance of more energetic blue light. On the other hand, plants on planets orbiting stars much fainter and redder than the Sun might look black. Hence, astrobiologists seeking signs of life on planets outside the Solar System may want to look for colors reflected by planetary vegetation that is colored differently than the green wavelengths found on Earth (NASA/GSFC ; Spitzer ; ; ;; and ).
Introduction to Spectroscopy - SpectraSchool
Life on earth receives the blessings of the light emitted by the sun. The energy that reaches the earth from the sun is about 2 calories per square centimeter per minute, the figure known as solar constant. Calculations based on this figure indicate that every second the sun emits as much energy into space as burning 10 quadrillion (10,000 trillion) tons of coal. The greatest of the sun's gifts to earth is photosynthesis by plants. When a material absorbs the energy of light, the light is changed into heat, thereby raising the object's temperature. There are also cases where fluorescence or phosphorescence is emitted, but most of the time materials do not change. Sometimes, however, materials do chemically react to light. This is called a "photochemical reaction." Photochemical reactions do not occur with infrared light, but happen primarily when visible light and ultraviolet rays, which have shorter wavelengths, are absorbed.
