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 .
Light is shined into a glass rod. To guarantee the total internal reflection (TIR) happens to all the possible rays, what is the minimum index of refraction n for the glass?
Illustrate briefly the significance of entropy? Determine the work done when 2 mole of an ideal gas expands isothermally and reversible from 10 atm. To 2 atm. Pressure at 27 0 C
