What is the maximum frequency of visible light, given visible light has wavelengths between 400 nm and.......? Maximum frequency implies minimum wavelength as frequency x wavelength = velocity Velocity = 3 x 10^8 m/s Minimum wavelength = 400 nm = 400 x 10^(-9) m = 4 x 10^(-7) m So, frequency = 3 x 10^8 / 4 x 10^(-7) = 0.75 x 10^15 Hertz.

Visible and Ultraviolet Spectroscopy Electromagnetic radiation such as visible light is commonly treated as a wave phenomenon, characterized by a wavelength or frequency. Wavelength is defined on the left below, as the distance between adjacent peaks (or troughs), and may be designated in meters, centimeters or nanometers (10-9 meters). Frequency is the number of wave cycles that travel past a fixed point per unit of time, and is usually given in cycles per second, or hertz (Hz).

- The longer wavelengths (red) and the shorter wavelengths (blue) are separated. Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres, or 4.00 × 10−7 to 7.00 × 10−7 m, between the infrared and the ultraviolet. This wavelength means a frequency range of roughly 430–750 terahertz. The main source of light on Earth is ...

Lesson: Visible Light and the Electromagnetic Spectrum The electromagnetic spectrum can be considered from another perspective — in nanometers — specifically from 400 nm to 700 nm. Each color in this visual range has a different wavelength. Red has the longest wavelength (700 nm) and violet has the shortest wavelength (400 nm).

Sound Becomes Light The electrical signals gave off radiation, or light waves, in the terahertz frequency. According to Evan Reed, one of the authors of the study, converting sound to light itself is novel, because there is only a very narrow frequency range -- around 100 GHz to 10 THz -- where sound and light waves overlap.

What is relationship between the frequency of light and its color? Red colored light is longer wavelength of light and visible violet light is shorter wavelength. For a cool chart and more in depth descriptin of the EM spectrum check out the Goddard Space Center's special page on this topic. The higher the frequency the more blue the light. The lower the frequency the more red the light. Colour, physical phenomenon of light or vision associated with the various wavelengths in the visible portion of the electromagneticspectrum. As a sensation experienced by human beings and some animals, perception of colour is a complex neurophysiological process.

David Terr's Website Ultraviolet Light Ultraviolet (UV) light is light with higher frequency (lower wavelength) than visible light. UV light has frequencies ranging from 8*10 14 to 3*10 16 Hz (800 THz to 30 PHz) and wavelengths from 10 -8 m to 3.8*10 -7 m (10 nm to 380 nm).

Electromagnetic spectrum Visible light is a small fraction of the entire electromagnetic spectrum with wavelengths ranging from 380 nm (nanometres or 10-9 m) to 740 nm. The whole bandwidth of the spectrum is illustrated in the following image. All the different types of electromagnetic radiation consist of photons of a specific wavelength. All objects that are warmer than their surrounding (that includes all the astronomical objects like stars, nebulae, planets, etc.) emit photons within a certain range of different wavelengths.

Visible spectrum White light is dispersed by a prism into the colors of the visible spectrum. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.A typical human eye will respond to wavelengths from about 390 to 700 nm.In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz.isible wavelengths pass through the  optical window , the region of the electromagnetic spectrum that allows wavelengths to pass largely unattenuated through the Earth's atmosphere. An example of this phenomenon is that clean air scatters blue light more than red wavelengths, and so the midday sky appears blue.

Which color of the visible light portion of the the electromagnetic spectrum has the highest frequency and the most energy? The visible spectrum : - red, orange, yellow, green, blue, violet. The blue end of the spectrum has a shorter wavelength, higher frequency and more energy than the red end o…f the spectrum. Thus violet light has the highest frequency and most energy.

Wavelength In a dispersive medium, the phase speed itself depends upon the frequency of the wave, making the relationship between wavelength and frequency nonlinear. In the case of electromagnetic radiation —such as light—in free space, the phase speed is the speed of light, about 3×10 8 m/s. Thus the wavelength of a 100 MHz electromagnetic (radio) wave is about: 3×10 8 m/s divided by 10 8 Hz = 3 metres. The wavelength of visible light ranges from deep red, roughly 700 nm, to violet, roughly 400 nm (for other examples, see electromagnetic spectrum).

What is the maximum frequency of visible light, given visible light has wavelengths between 400 nm and.......? Best Answer: The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 700 nm. In terms of frequency, this corresponds to a band in the vicinity of 430–790 THz. If the shortest wavelength is taken as 400 nm, the maximum frequency is 750 THz. (1 THz = 10^12 Hz)

Wavelength Range of Visible Light Our eyes are designed to detect a small portion of the electromagnetic spectrum. This part of the spectrum is called the visible light region. The visible light region ranges in wavelengths from about 380 or 400 nm to 700 or 780 nm depending on which source is used. In fact it also depends on the sensitivity of a specific persons eyes. Light waves travel at very high speeds and are absorbed or reflected by various objects.
