Discovery of X-rays

1. An early version of the cathode ray tubes used in older televisions and monitors
3. First type of practical x-ray tube to employ the principle of thermionic emission
5. It is made up of particles with mass and energy, some of which may or may not carry an electric charge.
6. The visible or invisible radiation released by certain substances in response to incident short-wavelength radiation such as X-rays or ultraviolet light.
8. Positive or oxidizing electrode that acquires electrons from the external circuit and is reduced during the electrochemical reaction.
9. the unique capability to remove electrons from atoms and molecules in the matter through which they pass
10. It could create a fluorescent effect in barium platinocyanide even when blocked by a sheet of cardboard
12. Originally named niton after the Latin word for shining, “nitens,”
13. energy that comes from a source and travels through space at the speed of light
14. A specialized imaging gadget that generates viewable X-rays without the requirement for X-ray photography or development
15. It is connected to the positive side of the high voltage in the crookes tube

2. Form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays
4. It fluoresces in the presence of x-rays and gamma rays
7. a picture produced on a sensitive surface by a form of radiation other than visible light
11. A stream of electrons emitted from the negative electrode of a discharge tube containing a low-pressure gas, or electrons emitted from a heated filament in certain electron tubes.
