WebShort answer: a photon is a particle of light. Longer answer: light is energy. Sometimes we think of light as being a wave in the form of an electro-magnetic wave but other times it can be described as a particle. A photon in this case, is 1 unit of light with a variable amount of energy which depends on its frequency. WebThis visible light region consists of a spectrum of wavelengths that range from approximately 700 nanometers (abbreviated nm) to approximately 400 nm. Expressed in …

WebSep 12, 2024 · The assigned frequencies for AM broadcasting are 540 to 1600 kHz, and for FM are 88 MHz to108 MHz. Figure 16.6. 2: Electromagnetic waves are used to carry communications signals by varying the wave’s amplitude (AM), … WebIn the visual system, a light waves wavelength is generally associated with color, and its amplitude is associated with brightness. Between these pulses there is what appears to be noise. Violet has the shortest visible wavelength in the visible spectrum (~ 400 nm), and red has the longest (700 nm). Given that the human voice falls in this ... thomas v bpe

WebIn physics, a continuous spectrum usually means a set of achievable values for some physical quantity (such as energy or wavelength), best described as an interval of real numbers. It is the opposite of a discrete spectrum, a set of achievable values that are discrete in the mathematical sense where there is a positive gap between each value. WebThe electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. WebWavelength and frequency are inversely proportional: As the wavelength increases, the frequency decreases. The inverse proportionality is illustrated in Figure 6.3.This figure also shows the electromagnetic spectrum, the range of all types of electromagnetic radiation.Each of the various colors of visible light has specific frequencies and … uk legislation for administering medication
