Applications of GMR GMR sensors find a wide range of applications: Fast and accurate position and motion sensing of mechanical components in precision engineering and robotics. Missile Guidance Position and motion sensing in computer video games. Key Hole Surgery and post operative care.
Ultraviolet Light Ultraviolet (UV) light is light with higher frequency (lower wavelength) than visible light. UV light has frequencies ranging from 8*10 14 to 3*10 16 Hz (800 THz to 30 PHz) and wavelengths from 10 -8 m to 3.8*10 -7 m (10 nm to 380 nm).
#2. John Creighto. Visible light has more energy per photon but the light that comes from the sun is spreads out so it is at a much lower intensity then it would be from a black body emission. If you think that infrared light is hotter then try putting you hand on a light bulb, a red hot stove burner or a white hot welding rod.
