The Electromagnetic and Visible Spectra
In the lesson you learned about the visible spectrum, which is only one part of the electromagnetic spectrum.
Electromagnetic spectrum involved in photosynthesis …
Photosynthesis is the biochemical process by which plants use light to generate fuel and activate various growth mechanisms. The spectral range of light that induces photosynthesis is called Photosynthetically Active Radiation (PAR). PAR is visible light that is measured from 400 to 700 nanometers (nm) and includes Violet, Blue, Green, Yellow, Orange and Red. Of these colors, Violet to Blue (400 to 500 nm) is associated with vegetating growth and Orange to Red (600 to 700 nm) is associated with flowering growth.
For example, different detectors are sensitive to different wavelengthsof light. In addition, not all light can get through the Earth's, so for some wavelengths we have to use telescopesaboard . Even the way we collect the light can changedepending on the wavelength. Astronomers must have a number of different telescopes and detectors to study the light from celestial objects across the electromagnetic spectrum.
Also referred to as plant lights, grow lights come from the series of sophisticated human creations; they give off light beams, making up electromagnetic spectrum and UV rays that are ideal for the procedure called the photosynthesis, or in the terms of botany, the plant development.
Together, all the types of electromagnetic radiation make up the
are the main photosynthetic pigments.

As we can see, there is a close relationship between the action spectrum and absorption spectrum of photosynthesis. There are many different types of photosynthetic pigments which will absorb light best at different wavelengths. However the most abundant photosynthetic pigment in plants is chlorophyll and therefore the rate of photosynthesis will be the greatest at wavelengths of light best absorbed by chlorophyll (400nm-525nm corresponding to violet-blue light). Very little light is absorbed by chlorophyll at wavelengths of light between 525nm and 625 (green-yellow light) so the rate of photosynthesis will be the least within this range. However, there are other pigments that are able to absorb green-yellow light such as carotene. Even though these are present in small amounts they allow a low rate of photosynthesis to occur at wavelengths of light that chlorophyll cannot absorb.
Introduction. The existence of infrared or invisible light is difficult to demonstrate convincingly. We use invisible light (electromagnetic radiation) all over TV/VCR remote controls, wireless computer connections, radio and TV transmissions, microwaves for communications and cooking. Our eyes can detect only a small part of this electromagnetic spectrum.
