What is the range of visible of light?
380 to 700 nanometers
The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
What is the range of cosmic rays?
Cosmic ray is the term given to high energy radiation which strikes the Earth from space. Some of them have ultrahigh energies in the range 100 – 1000 TeV. Such extreme energies come from only a few sources like Cygnus X-3.
Where can cosmic rays be found?
Cosmic rays are high-energy protons and atomic nuclei that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies.
What do cosmic rays consist of?
Current science. We know today that galactic cosmic rays are atom fragments such as protons (positively charged particles), electrons (negatively charged particles) and atomic nuclei. While we know now they can be created in supernovas, there may be other sources available for cosmic ray creation.
Where do you find visible light?
The Sun
Cones in our eyes are receivers for these tiny visible light waves. The Sun is a natural source for visible light waves and our eyes see the reflection of this sunlight off the objects around us. The color of an object that we see is the color of light reflected. All other colors are absorbed.
How are visible rays produced?
Visible light is part of radiation emitted by the sun. These rays can be produced by flame, bulb and incendencent lamps also. This is part of electromagnetic spectrum detected by human eye. (ii) Due to visible light we can see object around us.
What are examples of ultraviolet rays?
Ultraviolet radiation or UV radiation comes from the sun in sunlight. About ten percent of the total light output of the sun consists of ultraviolet radiation. Tanning beds and lamps also emit ultraviolet radiation. Tanning lamps and beds are also sources of UV rays.”
Are cosmic rays a form of light?
Although the name would suggest that cosmic rays are some form of electromagnetic radiation, they are actually subatomic particles travelling at significant fractions of the speed of light.
