A difference of 2.3 eV separates two energy levels in an atom. What is the frequency of radiation emitted when the atom make a transition from the upper level to the lower level?

In a hydrogen like atom electron make transition from an energy level with quantum number n to another with quantum number (n - 1) if n gtgt1 , the frequency of radiation emitted is proportional to :

"with increase in frequency of light incident number of electrons emitted increase"-True or false?

Statement-1: As light travels from one medium to another, thhe frequency of light doesn't change. Statement-2: Frequency is the characteristic of source.

Obtain an expression for the frequency of radiation emitted when a hydrogen atom de-excites from level n to level (n–1). For large n,show that this frequency equals the lassical frequency of revolution of the electron in the orbit.

The work function of Silver and sodium are 4.6 and 2.3 eV, respectively . The ratio of the slope of the stopping potential versus frequency plot for silver to that of sodium is
