Light Spectrum Graph
The ancient greeks recognized that light traveled in straight lines and studied some of its properties including reflection and refraction the study of light continued and during the 16th and 17th centuries conflicting theories regarded light as either a wave or a particle.
Light spectrum graph. Spectral colors are generally produced by monochromatic light i e. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Colour light bulb chart think beyond white led grow lights ultimate light bulb test incandescent commercial lighting calculating the emission spectra from full spectrum fluorescent light. For most of history visible light was the only known part of the electromagnetic spectrum.
The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges commonly. Visible light of a single wavelength. Electromagnetic spectrum the entire distribution of electromagnetic radiation according to frequency or wavelength although all electromagnetic waves travel at the speed of light in a vacuum they do so at a wide range of frequencies wavelengths and photon energies. The spectrum appears continuous.
How do plants respond to light. However the approximate ranges of wavelength and frequency can be used to specify the difference. In terms of frequency this corresponds to a band in the vicinity of 405 790 thz. Photosynthesis is the process by which plants and other organisms convert light energy into chemical energy.
Electromagnetic radiation in this range of wavelengths is called visible light or simply light a typical human eye will respond to wavelengths from about 380 to 740 nanometers. It is also known as the optical spectrum of light or the spectrum of white light. Light spectrum can mean the visible spectrum the range of wavelengths of electromagnetic radiation which our eyes are sensitive to or it can mean a plot or chart or graph of the intensity. Plants use light for photosynthesis and photomorphogenesis.
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. This grow light spectrum chart illustrates how par coincides with visible light spectrum.
