Light Facts
- In physics, light refers to electromagnetic radiation.
- Other animals can see parts of the spectrum that humans can�t.
- UV light can be used to show things the human eye can�t see, coming in handy for forensic scientists.
- The wavelength of infrared light is too long to be visible to the human eye.
10 Facts about light and lenses
- The light we see on Earth is a form of energy from the Sun.
- We call the light we can see visible light or white light.
- You don't need to wait for rain to see a rainbow.
- Refraction is how lenses in eye glasses, telescopes and binoculars work.
As a wave, light can expand and radiate in all directions, interfere with other waves, bend around corners, carry energy and momentum, and interact with matter. 2. Not only is light a wave, it is an electromagnetic wave. As such, light can travel without a medium.
What are some interesting facts about white light : White light, including all its combined colors, represent a small part of the electromagnetic spectrum. It is the only form of light we can see because of its wavelength. Our eyes can only detect wavelengths between 380 and 700 nanometers. Violet light has the shortest wavelength, and red light has the largest.
What are 10 facts about light
- Light sources can be natural or humanly constructed.
- Light is made up of all the colours mixed together.
- Things appear a certain colour because it's the only colour that is reflected.
- Light is a beam of energy.
- Light is measured in wavelengths on the electromagnetic spectrum.
What is one fact about visible light : Visible light waves are the only wavelengths of the electromagnetic spectrum that humans can see. The different wavelengths of visible light are seen as the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.

All electromagnetic radiation is light, but we can only see a small portion of this radiation—the portion we call visible light. Cone-shaped cells in our eyes act as receivers tuned to the wavelengths in this narrow band of the spectrum.
What are the 7 colors of light
Sunlight, or visible light, is made of all the rainbow colors: red, orange, yellow, green, blue, indigo, and violet.Visible light or white light is the part of the electromagnetic spectrum that can be detected by the human eye.Light is not only responsible for allowing us to see our surroundings but also has other biological effects and influences the sleep/wake cycle, among other things. Light has long been used for medical and cosmetic purposes. Many lasers and IPL devices ("flash lamps") operate with different wavelengths of light.
In short – light itself is not visible, but it allows us to see because our eyes are sensitive to light and our brains process the light signals that went into our eyes. So light hits an object and is reflected back into our eyes, and that allows us to see the object.
What is the most amazing fact about light : Light travels incredibly fast. Nothing can travel as fast as light. miles per second). Light travels faster than sound so that's why we see lightning before we hear the thunder.
Why can’t humans see light : The only way your eye can see things is if that thing sends photons to your eye. You can't see the photons that light up the object… because if they did, you would not be seing the object, but the original light source. In a house the only way you can see light beams is from dust floating in the air.
Can we see light with our eyes
In short – light itself is not visible, but it allows us to see because our eyes are sensitive to light and our brains process the light signals that went into our eyes. So light hits an object and is reflected back into our eyes, and that allows us to see the object.
The colors of visible light, often referred to as ROY G BIV (for red, orange, yellow, green, blue, indigo, and violet), are a small portion of the entire electromagnetic spectrum. Light can be thought of as a stream of packets of energy called photons.If we judge by the most prominent color, the sky is violet. But the sky appears blue due to the limitations of our eyes. Our sensitivity to light decreases as we reach the shortest wavelengths of the visible spectrum. The violet is there, but our eyes detect it only weakly.
What colors can humans not see : We see our world in a huge variety of colour. However, there are other “colours” that our eyes can't see, beyond red and violet, they are: infrared and ultraviolet.
