1、什么是同步辐射光源?What is a synchrotron radiation light source? " Synchrotron radiation" refers to a continuous band of electromagnetic spectrum including infrared, visible light, ultraviolet, and X-rays. This light has been called "synchrotron radiation", since it was accidentally discovered in...
Light energy has both electric and magnetic fields, so it is often referred to as electromagnetic radiation. Light waves come in many sizes, or wavelengths. The light we can see is only a very small part of the spectrum of light waves that exist. Ultraviolet light is part of the ...
