WAVELENGTHS OF IVISIBLE TV

For orange color, the wavelength range is from 610 to 590 nm and frequency ranges from 510 to 480 THz.For the red color, the wavelength range is from 750 to 610 nm and frequency ranges from 480 to 405 THz.

But these waves can be observed like the rainbow colors wherever each color contains a different wavelength. Once this range is crossed, then the human eye cannot observe the electromagnetic waves. The detection range of the light spectrum can range from 400 nm to 700 nm. The range of visible spectrum in the electromagnetic spectrum ranges from the region of IR to the ultraviolet. The visible spectrum is a visible area of the electromagnetic wave and it is noticeable to the eyes of a human.

For radio rays, the frequency range is 1 mm.

For microwaves rays, the frequency range is 3*1011 – 1013 and wavelength range is less than 1mm to 25 μm.

For IR rays, the frequency range is 1013 to 1014 and the wavelength range is 2.5 μm to 2.5 μm.

For near IR rays, the frequency range is 1*1014 – 4*1014and wavelength range is less than 2.5 μm – 750 nm.

For visible rays, the frequency range is 4 to 7.5X1014 and wavelength range is less than 750 nm – 400 n.

For UV–rays, the frequency range is 1015 to 1017 and the wavelength range is 400 nm to 1 nm.

For x-rays, the frequency range is 1017 to 1020 and the wavelength range is 1 nm to 1 pm.

For gamma rays, the frequency range is 1020 to 1024 and the wavelength range is 10-12 m.

Similarly, electromagnetic waves using fewer frequencies and long wavelengths include microwaves, IR, TV and radio waves. The waves like electromagnetic with high frequencies & shorter wavelengths include different rays like UV, gamma and X-rays. In a complete electromagnetic spectrum, the light makes up only a small portion. The wavelength range of visible light ranges from 400 nanometers to 700 nanometers. The categorization of electromagnetic waves can be done based on the frequency otherwise wavelength. The units of wavelength are micrometers or nanometers. A wavelength can be defined as the distance between two crests and troughs. These waves include consecutive troughs and crests. We know that light doesn’t travel in a straight line but travels in the form of a transverse wave. All these are forms of light and the study of this is called optics. There are different kinds of radiations available like radio, gamma, microwaves, and x-rays. Sometimes in physics, any wavelength’s electromagnetic radiation refers to the term light. Experimentally, the light speed is found in vacuum to be 299,792, 458 m/sec or 3X108 m/sec. Generally, the term light refers to visible light and it is visible to the human eye. When electromagnetic radiation occurs within a particular section of the electromagnetic spectrum is known as light.
