Light Spectrum

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.

Light spectrum. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. The order of colors is red orange yellow green blue indigo and violet. The electromagnetic em spectrum is the range of all types of em radiation radiation is energy that travels and spreads out as it goes the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.

The visible spectrum is always the same for a rainbow or the separated light from a prism. Visible light is the part of the spectrum from 380nm to 780nm. Light from 400 700 nanometers nm is called visible light or the visible spectrum because humans can see it light outside of this range may be visible to other organisms but cannot be perceived by the human eye. 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 electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges commonly. Light light the electromagnetic spectrum. 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. In the visible spectrum of light the color of the light depends on the frequency.

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. For most of history visible light was the only known part of the electromagnetic spectrum. Essentially that equates to the colors the human eye can see. Light is measured in nanometers nm.

Light spectrum is the many different wavelengths of energy produced by a light source. The human eye sees color over wavelengths ranging roughly from 400 nanometers violet to 700 nanometers red. In terms of frequency this corresponds to a band in the vicinity of 405 790 thz. Each nanometer represents a wavelength of light or band of light energy.

The other types of em radiation that make up the.
