Question

How are x ray produced

Answer 1

The production of x-rays requires a rapidly moving stream of electrons that are suddenly decelerated or stopped. The source of electrons is the cathode, or negative electrode. Electrons are stopped or decelerated by the anode, or positive electrode. Electrons move between the cathode and the anode because there is a potential difference in charge between the electrodes.


Characteristics of X-Rays


X-rays are invisible.

X-rays are electrically neutral. They have neither a positive nor a negative charge. They cannot be accelerated or made to change direction by a magnet or electrical field.

X-rays have no mass.

X-rays travel at the speed of light in a vacuum.

X-rays cannot be optically focused.

X-rays form a polyenergetic or heterogenous beam.

The x-ray beam used in diagnostic radiography comprises many photons that have many different energies.

X-rays travel in straight lines.

X-rays can cause some substances to fluoresce.

X-rays cause chemical changes to occur in radiographic and photographic film.

X-rays can be absorbed or scattered by tissues in the human body.

X-rays can produce secondary radiation.

X-rays can cause chemical and biologic damage to living tissue.

Answer 2

They are emitted by sun rays ,but in daily life x rays are produced when electrons strike on metal target.
