X-rays are a form of electromagnetic radiation, as are radio waves, microwaves, visible light and ultraviolet. ' all travel as waves, but have different wavelengths.
X-ray waves are much shorter and more energetic in visible light waves. X-rays are invisible because their waves are too short for our eyes to see.
X-rays are made when negatively charged particles
teal led electrons are fired at a heavy plate made of the metal tungsten. The plate bounces back X-rays.

An X-ray gives a dear picture of the inside of the chest, showing the ribs, the spine and the branching airways in the lung. Any lung problems and blockages show up as white shadows.
Even though they are invisible to our eyes, X-rays register on photographic film.
X-rays are so energetic that they pass through some body tissues like a light through a net curtain.
To make an X-ray photograph, X-rays are shone through the body. The X-rays pass through some tissues and turn the film black, but are blocked by others, leaving white shadows on the film.

Each kind of tissue lets X-rays through differently. Bones are dense and contain calcium, so they block X-rays and show up white on film. Skin, fat, muscle and blood let X-rays through and show up black on film.
X-ray radiation is dangerous in high doses, so the beam is encased in lead, and the radiographer who takes the X-ray picture stands behind a screen.
X-rays are very good at showing up bone defects. So if you break a bone, it will be probably be X-rayed.
X-rays also reveal chest and heart problems.
