Related to spectrum: Light spectrumspec·trum (spĕk′trəm) n. pl. spec·tra (-trə) or spec·trums 1. Physics a. The entire range over which some measurable property of a physical system or phenomenon can vary, such as the frequency of sound, the wavelength of electromagnetic...
The meaning of SPECTRUM is a continuum of color formed when a beam of white light is dispersed (as by passage through a prism) so that its component wavelengths are arranged in order. How to use spectrum in a sentence.
The entire range of electromagnetic radiation. At one end of the spectrum are gamma rays, which have the shortest wavelengths and high frequencies. At the other end are radio waves, which have the longest wavelengths and low frequencies. Visible light, with intermediate wavelengths and frequencies,...
The meaning of PURE SPECTRUM is a spectrum in which the dispersion is highly discriminative so that at each point the light is practically monochromatic.
Spectrum definition: an array of entities, as light waves or particles, ordered in accordance with the magnitudes of a common physical property, as wavelength or mass. See examples of SPECTRUM used in a sentence.
Spectrum, in physics, the intensity of light as it varies with wavelength or frequency. An instrument designed for visual observation of spectra is called a spectroscope, and an instrument that photographs or maps spectra is called a spectrograph. Learn
Solar spectrum, the spectrum of solar light, especially as thrown upon a screen in a darkened room. It is characterized by numerous dark lines called Fraunhofer lines. Thermal spectrum, a spectrum of rays considered solely with reference to their heating effect, especially of those rays which pro...
White light is formed by combining all the frequencies, wavelengths, or colors of the visible light spectrum. Objects that emit white light, such as the sun, stars, or fluorescent bulbs, are emitting all the ranges of frequencies or colors of the visible light spectrum. What is the average ...
Both light intensity and spectrum (280–800 nm) affect photosynthesis and, consequently, the formation of reactive oxygen species (ROS) during photosynthetic electron transport. ROS, together with antioxidants, determine the redox environment in tissues and cells, which in turn has a major role in ...
