A diagram of the electromagnetic spectrum, showing various properties across the range of frequencies and wavelengths. The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band.
Faraday proposed in 1847 that light was a high-frequency electromagnetic vibration, which could propagate even in the absence of a medium such as the ether. [40] Faraday's work inspired James Clerk Maxwell to study electromagnetic radiation and light. Maxwell discovered that self-propagating electromagnetic waves would travel through space at a ...
Spectral imaging may use the infrared, the visible spectrum, the ultraviolet, x-rays, or some combination of the above. It may include the acquisition of image data in visible and non-visible bands simultaneously, illumination from outside the visible range, or the use of optical filters to capture a specific spectral range.
The optical atmospheric window is the optical portion of the electromagnetic spectrum that passes through the Earth's atmosphere, excluding its infrared part; [10] although, as mentioned before, the optical spectrum also includes the IR spectrum and thus the optical window could include the infrared window (8 – 14 μm), the latter is ...
An atmospheric window is a region of the electromagnetic spectrum that can pass through the atmosphere of Earth. The optical , infrared and radio windows comprise the three main atmospheric windows. [ 2 ]
Original Edit1 with continuous colour scale Reason Ultra-enc value + svg + high quality (it's a pity the article isn't in the same shape) Proposed caption The electromagnetic spectrum encompasses all electromagnetic radiation - ranging from radio waves through microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays in order of increasing frequency.
