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 wavelength of visible light is typically measured in nanometres, with 1,000,000,000 nanometres making up a metre. It runs from approximately 400 nm (violet) to 700 nm (red). May 27, 2024 · The electromagnetic spectrum is a fundamental concept in physics, encompassing all types of electromagnetic radiation. Radio waves, visible light, and gamma waves for example, each have different ranges of wavelengths within the electromagnetic spectrum. The visible part of the spectrum may be subdivided according to color, with red at the long wavelength end and violet at the short wavelength end, as illustrated (schematically) in the following figure. They have have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers. Electromagnetic spectrum consists of various types of electromagnetic radiations having different wavelengths (or different frequencies). The electromagnetic spectrum is a range of frequencies, wavelengths and photon energies covering frequencies from below 1 hertz to above 10 25 Hz, corresponding to wavelengths which are a few kilometres to a fraction of the size of an atomic nucleus in the spectrum of electromagnetic waves. Visible light makes up just a small part of the full electromagnetic spectrum. Red light has a wavelength of ~700 nm, and a frequency of ~4. The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. White light may be separated into its spectral colors by dispersion in a prism. 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. White light is dispersed by a glass prism into the colors of the visible spectrum. The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. 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.
