Physics: how x-rays are generated
Self-tutoring about physics: the tutor looks at x-ray generation.
One type of x-ray generator is a vacuum tube containing a heated plate at one end, and the receiving plate at the opposite end. Around the outside of the tube, the plates are connected by a wire.
The heated plate is brought to such a high temperature that it starts to release electrons. They hit the receiving plate with such high velocity that it emits x-rays to disperse the energy. Their emission can be directed by angling the receiving plate’s face relative to the heated one.
