Does white light exist?
White light is defined as the complete mixture of all of the wavelengths of the visible spectrum. This means that if I have beams of light of all of the colors of the rainbow and focus all of the colors onto a single spot, the combination of all of the colors will result in a beam of white light.
Do we only see 1 percent?
The entire rainbow of radiation observable to the human eye only makes up a tiny portion of the electromagnetic spectrum – about 0.0035 percent. This range of wavelengths is known as visible light.
What uses visible light?
Visible light is the light we can see, so is used in photography and illumination. It is also used in fibre optic communications, where coded pulses of light travel through glass fibres from a source to a receiver.
How is gamma radiation used in everyday life?
Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry. Shielding against gamma rays is essential because they can cause diseases to skin or blood, eye disorders and cancers.
What color are gamma rays?
A gamma ray packs at least 10,000 times more energy than a visible light ray. Unlike the Incredible Hulk, gamma rays are not green — lying as they do beyond the visible spectrum, gamma rays have no color at all that we can describe.
Is gamma a wave or particle?
Gamma radiation is electromagnetic radiation that is emitted by an unstable nucleus of an atom during radioactive decay. A nucleus in an unstable state may fall to a more stable state by the emission of energy as gamma radiation. The radiation has a dual nature, that of a wave and a particle with zero mass at rest.
Can gamma rays produce electricity?
Yes, we can convert gamma rays into electrical energy and hence electricity. Research has shown that semi-conductors like Si wafers (technically silicon cells) have been excited using gamma rays to generate an output voltage (or/and current) thereby producing power.
