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).
Likewise (and restricting ourselves to optical light for the moment), blue light and red light are both just light, but the blue light has a higher frequency of vibration (or a shorter wavelength) than the red light. The colors of the familiar rainbow of visible light correspond to differing wavelengths of the light, here shown on a nanometer scale.
