A Chart Of The Chemical Elements That Displays Them In Rows Horizontally In Order Of Increasing Atomic Number And Vertically According To Similarity Of The Chemical Properties Of Their Atoms.
There are some methods that differentiate waves; one thing is by its medium.
Electromagnetic waves did not require a medium for transmission such as in a
vacuum while mechanical waves require a medium to travel such as air, water or
anything that can serve as a transmission aid.
The most common sample of EM waves in
telecommunication is radio,
light and infra-red signals. An example of a mechanical wave is a sound
wave, which requires air to travel. Oscillating molecules made the
sound waves.
Dmitri Mendeleev was the creator and therefore organizer of the periodic table.
