Visible Light Waves

In terms of frequency this corresponds to a band in the vicinity of 405 790 thz.

Visible light waves. Essentially that equates to the colors the human eye can see. It is also known as the optical spectrum of light or the spectrum of white light. Electromagnetic waves or electromagnetic radiation are waves made of oscillating magnetic and electric fields and include radio waves microwaves infrared visible light ultraviolet x rays. Red has the longest wavelength and violet has the shortest wavelength.

Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye. 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. Visible light is a form of electromagnetic em radiation as are radio waves infrared radiation ultraviolet radiation x rays and microwaves. Billionths of a metre.

When all the waves are seen together they make white light. Each color has a different wavelength. Generally visible light is defined as the. Light electromagnetic radiation that can be detected by the human eye electromagnetic radiation occurs over an extremely wide range of wavelengths from gamma rays with wavelengths less than about 1 10 11 metre to radio waves measured in metres.

The outer most layer of the sun s atmosphere the corona can be seen in visible light. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Within that broad spectrum the wavelengths visible to humans occupy a very narrow band from about 700 nanometres nm. The sun is the dominant source for visible light waves our eyes receive.

But it is so faint it cannot not be seen except during a total solar eclipse because the bright photosphere overwhelms it. It ranges in wavelength from approximately 400 nanometers 4 x 10 7 m which is violet to 700 nm 7 x 10 7 m which is red. 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.
