Light is a type of energy.It is a form of electromagnetic radiation of a wavelength which can be detected by the human eye.It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun.Animals can also see light. The spectrum includes radio waves, microwaves, infrared light, visible light, ultraviolet, x-rays and gamma rays, but only visible light, which we interpret as colors, can be seen. The source of the visible light is the sun. 4. Ultraviolet (UV) light has shorter wavelengths than visible light. Light Facts. We will not distinguish the colors that add beauty to a certain thing. visible light is one way energy uses to get around and allows us to see. Light Facts. By David Weedmark. Hence, it is called visible light. People have been interested to study the visible light since the ancient era. When all the waves are seen together, they make white light. The visible spectrum is always the same for a rainbow or the separated light from a prism. Other animals can see parts of the spectrum that humans can’t. Wiki User 2012-04-23 00:42:31. Visible light waves are the only wavelengths of the electromagnetic spectrum that humans can see. It is made up of tiny photons, each contains a lot of energy. Essentially, that equates to the colors the human eye can see. Visible light waves are the only electromagnetic waves we can see. With methods to see these high-energy types of light, scientists get a … A light wave is made up of energy in the form of magnetic and electric fields. People have been interested to study the visible light since … Of all the forms of radiation and light on the electromagnetic spectrum, humans can only visibly see a very small amount of light. Hence, … 2. It is used to define the wavelength within the visible spectrum. So approximately one-third of all visible light is considered high-energy visible (HEV) or "blue" light. The refractive index of water is 1.3 while the refractive index of air is … When we talk about electromagnetic spectrum, we should never separate it with the visible light.

Visible light waves are the only electromagnetic waves we can see.

Although UV waves are invisible to the human eye, some insects, such as bumblebees, can see them. Check Also: 10 Facts about electric microscope. Key points about blue light A wavelength, the distance between the crests of two waves, is often measured in units called nanometers. Updated April 29, 2018. Visible Light Waves. The intensity and wavelength are some characteristics of electromagnetic radiation. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye.

Red has the longest wavelength and violet has the shortest wavelength. Brighten your science knowledge with our fun light facts for kids. A fun way to remember this is by using the first letter in each color in order to spell out the name ROY G. BIV. All phenomena of visible light such as reflection, refraction, interference, and diffraction are also exhibited by non-visible wavelengths. The light we normally talk about in everyday life refers to the visible spectrum (the part of the electromagnetic spectrum that the human eye can see). In physics, light refers to electromagnetic radiation. It has a wavelength range of 380 to 740 nm. Understand how electromagnetic radiation works and discover the many fascinating properties of light. Ultraviolet rays have shorter wavelengths than visible light. Understand how electromagnetic radiation works and discover the many fascinating properties of light. All phenomena of visible light such as reflection, refraction, interference, and diffraction are also exhibited by non-visible wavelengths. Each color has a different wavelength. Think of ultraviolet light, which is the source of sunburns, or infrared light, which delivers heat. Visible light is just what it sounds like - the light waves you can see with your eyes.

The outer-most layer of the Sun's atmosphere, the corona, can be seen in visible light. There are several other wavelengths that we cannot see with just our eyes, but machines can detects some of these wavelengths.
