X-rays are commonly produced by accelerating (or decelerating) charged particles; examples include a beam of electrons striking a metal plate in an X-ray tube and a circulating beam of electrons in a synchrotron particle accelerator or storage ring.
Examine your computer for jacks and ports that support your audio device. The location of certain jacks and ports will vary depending on your computer's make and model. For example, most jacks on a desktop computer will be located in the back; whereas jacks on a laptop computer are usually located on its sides.
Example: An RCA jack can often be used to connect the analog output of a DVD player to the analog inputs located on the rear side of a television. The red and white colors represent the right and left stereo audio channels, respectively. A yellow connection (composite cable) is used to deliver the video signal.
