NUMERICAL QUESTIONS:

 

Q1: An electron is shifted from 4th orbit to 1st orbit, find out the wavelength of radiations emitted.

Q2. Calculate the energy of 3rd orbit of energy level in joules. (Charge of electron = 1.6 x 10-29)

 

Q3. What will be the wavelength of radiations, when an electron is transferred from 3rd orbit in Balmer series?

Q4: The frequency of photons released is 1.5 x 1033 estimates the magnitude of energy in joules.

Q5. What will be the radius of an atom having two energy levels?
