  • Electromagnetic spectrum and light — Astronoo

    Visible light is only a small range of electromagnetic vibrations that we find in the electromagnetic spectrum. Light refers to electromagnetic waves visible to the human eye, they are included in the wavelengths of 0.38 to 0.78 micron. 380 nanometers for violet to 780 nm for red. The light is closely linked to the concept of color.

  • Introduction to the Electromagnetic Spectrum and

      It is a well known fact that light is composed of electromagnetic radiation which is often treated as a wave phenomenon which has a defined wavelength. In a wave, wavelength is defined by the distance in a wave where the shape of the wave repeats and is usually determined by the distance between corresponding points of the same phase.Wavelength being defined as the distance, has the units of distance, i.e. meters (m), centimeters (cSee more on pharmaxchangefo

      The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.A typical human eye will respond to wavelengths from about 390 to 700 nm. In terms of frequency, this corresponds to a band in the vicinity of 430–790 THz.

      The electromagnetic spectrum (EMS) is the general name given to the known range of electromagnetic radiation. Wavelengths increase from approximately 10 18 m to 100 km, and this corresponds to frequencies decreasing from 3 × 10 26 Hz to 3 ×10 3 Hz. The image below shows the names given to different regions of the EMS.

      Visible Spectrum The visible region of the electromagnetic spectrum consists of photons with wavelengths from approximately 400 to 700 nm. The short wavelength cutoff is due to absorption by the lens of the eye and the long wavelength cutoff is due to the decrease in sensitivity of the photoreceptors in the retina for longer wavelengths.
