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).
Visible light is a form of electromagnetic radiation. Other forms of electromagnetic radiation are like light in many ways; they are just at different wavelengths that the human eye cannot see. Since wavelength is what makes the difference between colors in visible light, you might say other wavelengths of electromagnetic radiations are invisible colors of light. Radio, infrared, visible light, ultraviolet, X-rays, and gamma rays are all forms of electromagnetic radiation.
