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).
UV light cannot be seen by the naked eye whereas visible light such as sunlight entering a room can be seen. Fortunately we have the cornea (front of the eye) and the lens in the eye which absorb UV light and reduce the amount of UV rays reaching the retina (the back of the eye).
