If radiation having a frequency in the visible region of the EM spectrum reflects off an object, say, a bowl of fruit, and then strikes the eyes, this results in visual perception of the scene. The brain's visual system processes the multitude of reflected frequencies into different shades and hues, and through this … Ver mais The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic … Ver mais Electromagnetic waves are typically described by any of the following three physical properties: the frequency f, wavelength λ, or photon energy E. Frequencies observed in astronomy range from 2.4×10 Hz (1 GeV gamma rays) down to the local Ver mais Radio waves Radio waves are emitted and received by antennas, which consist of conductors such as metal rod Ver mais • Australian Radiofrequency Spectrum Allocations Chart (from Australian Communications and Media Authority) • Canadian Table of Frequency Allocations Archived 2008-12-09 at the Wayback Machine (from Industry Canada) Ver mais Humans have always been aware of visible light and radiant heat but for most of history it was not known that these phenomena were connected or were representatives of a more extensive principle.
