Frequency Of Visible Light

As a form of electromagnetic radiation light has properties in common with both waves and particles.

Frequency of visible light. Newton demonstrated that colour is a quality of light. It s just that we only see light in a limited range of frequencies. Visible light is usually defined as having wavelengths in the range of 400 700 nanometers nm or 4 00 10 7 to 7 00 10 7 m between the infrared with longer wavelengths and the ultraviolet with shorter wavelengths. Hence it is called visible light.

To understand colour therefore it is necessary to know something about light. Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye. The frequency of visible light is referred to as color and ranges from 430 trillion hertz seen as red to 750 trillion hertz seen as violet. Colour colour the visible spectrum.

In terms of frequency this corresponds to a band in the vicinity of 405 790 thz. The visible light spectrum is located within a wavelength range of 380 to 740 nanometers nm or frequency range of 405 to 790 terahertz thz. The frequency of visible light excerpted from spectrums by david blatner red light that is light that our human eyes perceive as red has a frequency of about 420 thz terahertz. Wavelength of the visible light ranges between 400 nm to 700 nm and here we come to know the wavelength of various colours of the visible spectrum of light.

If your car wheels revolved that quickly you. Visible light is from about 380 to 750 terahertz. Light at the lower end of the visible spectrum having a longer wavelength about 740 nm is seen as red. Light in the middle of the spectrum is seen as green.

Wavelength λ is the distance between two waves of energy traveling from one point to another point. Technically all frequencies are possible with light. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Visible light is a small portion of the electromagnetic spectrum.

Since visible light is a form of a wave it is defined by its characteristic wavelength and frequency. And light at the upper end of the. Frequency hz is some sort of vibration occurs during a particular period of time as either in a sound waves or in an electromagnetic field. Electromagnetic radiation in this range of wavelengths is called visible light or simply light a typical human eye will respond to wavelengths from about 380 to 740 nanometers.

The spectrum of visible light has about numerous different colours having different wavelengths. Again the full range of frequencies extends beyond the visible portion from less than 3 billion hertz as in radio waves to greater than 3 billion billion hertz 3 x 10 19 as in gamma rays.
