THOMSON'S ATOMIC MODEL:-
According to Thomson's atomic model positive charge is distributed uniformly over the entire body of the atom while the electrons are embedded in it. Similar to the seeds in a water melon.
Thomson's model failed to explain observed spectra emitted by an atom .
The energy needed to ionize an atom is known as ionization energy. It is the energy needed to make the electron jump from the present orbit to the infinite orbit.
What are single ends? The extreme fiber optics conductor is farthest from the illuminator. The bit which emits light or the end that lights up.
Can multiple illuminators change colors simultaneously? Yes. Usually the standard disc rotating motors are of the synchronous form, very reliable, and geared to the most suffi
