The spectrum of waves includes infrared rays, visible light, ultraviolet rays, and X-rays. Human eyes are only sensitive to the range that is between wavelength 780 nanometers and 380 nanometers in length.
Why is Water Blue? Water absorbs warm colors a long wavelength light and scatters the cooler colors (short wavelength light). Red light is absorbed strongly and blue light has the deepest penetration depth.
The Sun generates its energy by nuclear fusion of hydrogen nuclei into helium The proton-proton chain dominates in stars The Hydrogen Bomb
Parts of an Light Emitting Diode. LED. Unlike bulbs, LEDs do not generate heat and power loss through heating is practically nil.
