The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. The electromagnetic spectrum extends from below frequencies used for modern radio to gamma radiation at the short-wavelength end, covering wavelengths from thousands of kilometers down to a fraction of the size of an atom. The long wavelength limit is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length, although in principle the spectrum is infinite and continuous. Although some radiations are marked as N for no in the diagram, some waves do in fact penetrate the atmosphere, although extremely minimally compared to the other radiations Legend γ= Gamma rays MIR= Mid infrared HF= High freq. HX= Hard X-Rays FIR= Far infrared MF= Medium freq. SX= Soft X-Rays Radio waves LF= Low freq. EUV= Extreme ultraviolet EHF= Extremely high freq. VLF= Very low freq. NUV= Near ultraviolet SHF= Super high freq. VF/ULF= Voice freq. Visible light UHF= Ultra high freq. SLF= Super low freq. NIR= Near Infrared VHF= Very high freq. ELF= Extremely low freq.

Q. I red that the gravitational waves travel with speed of light, but it is not included in the electromagnetic spectrum. Do these waves has any frequencies as well? Asked by moravianhawk - Tue Sep 26 21:06:34 2006 - - 6 Answers - 0 Comments A. Gravity is a separate force from the electromagnetic force and at present the nature of it is unknown. It is thought to be governed by a theoretical particle called the graviton. The electromagnetic force is governed by the photon, which is the quantum of light. Sound also travels as waves and is not part of the electromagnetic spectrum.

I need the electromagnetic spectrum of fluorescent lamps?
Q. I need the spectrum (image), as well as lumens and colour temperature specifications, of the following lamps from Philips: TLK/40W (which is an UV lamp), Cool White 18W/840 and the Master TL-D Super 80 18W/827. I have tried a crazy lot of searches with poor results. Or ideas on what lamps to use, beside HID- an HPS lamps, would also help. It's for sustaining some Southern African trees (Acacia) indoors.

Go to a specialized lighting store and ask for lighting with a min. 0f equiv. 20,000 light bulbs...for Arcaia species. The guy should sell you the correct ones.
