The scientific definition of light is--a wavelength of electromagnetic radiation between 3,800 and 7,600 angstrom units to which the retina of the eye is sensitive and a part of the electromagnetic spectrum the brain interprets. That physical response of our eyes reacting to light, long before it could be defined as retina and wavelength, has engendered a light-defined vocabulary over centuries. For example, when we talk about the physical properties of light, we talk of, "the light at the end of the tunnel," "by the light of the moon."
What else can I help you with?
Does visible light have high or low energy?
Visible light has moderate energy compared to other forms of electromagnetic radiation. It falls within the range of wavelengths that are visible to the human eye, with shorter wavelengths of visible light corresponding to higher energy levels.
What do the visible colars of light represent?
The frequency range of visible light.
Are X-rays visible light?
No, x-rays are not visible light.
What has more energy a visible light or infrared light?
Visible light. It has a higher frequency so more energy.
The portion of the electromagnetic spectrum visible to the human eye is known as?
The (not surprising) name is "visible light."
In what ways is laser light different from visible light?
Laser light is different from visible light in several ways. Laser light is monochromatic, meaning it consists of a single color or wavelength, while visible light contains a range of colors. Laser light is also coherent, meaning its waves are in sync and travel in a straight line, unlike visible light which scatters in different directions. Additionally, laser light is intense and focused, making it useful for various applications such as cutting, welding, and medical procedures.
What is a textbook considered to visible light?
A textbook is considered opaque to visible light, meaning that it does not allow light to pass through it easily. The pages of the book absorb or reflect the light that hits them, making the text and images on the pages visible to the reader.
What is the literal meaning of the word lightning?
The word lightning derives from "lightening", something which sheds light. But its literal meaning is a visible discharge of static electricity in the sky.
What is the transparency of sulfur?
Sulfur is opaque to visible light, meaning it does not allow light to pass through it.
Does visible light have high or low energy?
Visible light has moderate energy compared to other forms of electromagnetic radiation. It falls within the range of wavelengths that are visible to the human eye, with shorter wavelengths of visible light corresponding to higher energy levels.
Optical telescopes are designed to collect and create images from is it white or visible light or x rays or infrared radiation or gamma rays?
An "optical" telescope would naturally collect light from optical wavelengths, meaning visible light from ~400-800nm.
What colors produce magenta light?
Magenta light is produced by mixing red and blue light. It is a non-spectral color, meaning it is not found in the visible spectrum of light as a single wavelength.
What is one difference between visible and non-visible light?
One difference between visible and non-visible light is that visible light can be seen by the human eye, while non-visible light, such as ultraviolet or infrared light, cannot be seen without special equipment.
What is the meaning photo chemistry?
Photochemistry is a branch of chemistry which study chemical reactions under irradiation with visible light.
What kind of light is normal light that you use?
The answer is visible light. Visible light is light that can be seen with a naked eye
Is ultraviolet light visible?
No, ultraviolet light is not visible to the human eye. It has a shorter wavelength than visible light, which makes it invisible.
Is visible light electromagnetic?
Yes. visible light is in the electromagnetic spectrum.
