Light which has a wavelength shorter than violet is named ultraviolet light. X-rays and gamma rays are sorts of light with even shorter wavelengths than ultraviolet. Light with a wavelength for a longer time than purple is called infrared light. Radio waves certainly are a sort of electromagnetic radiation which has a wavelength lengthier than infrared light.

By using the quantum theories of Planck and Einstein, Compton was able to describe light as equally a particle and also a wave, depending upon the way in which it had been examined.

The gap from your lens to the focus is called the focal length, file. A diverging lens spreads the beam out to ensure it appears being coming from your focal point.
