The transition from the state $$n = 4$$ to $$n = 3$$ in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from
Write the spectral symbols for the terms of a two-electron system consisting of one p electron and one d electron.
The transition from the state $$n = 4$$ to $$n = 3$$ in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from
Taking the wavelength of first Balmer line in hydrogen spectrum ($$n=3$$ to $$n=2$$) as $$660nm$$, the wavelength of the 2nd Balmer line ($$n=4$$ to $$n=2$$) will be:
Hydrogen atom is excited from ground state to another state with principal quantum number equal to $$4$$. Then the number of spectral lines in the emission spectra will be.
The transition from the state $$n=3$$ to $$n=1$$ in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from-
The energy of the em waves is of the order of 15 keV. To which part of the spectrum does it belong?
Electromagnetic waves of wavelength ranging from $$100\overset {\circ}{A}$$ to $$400 \overset {\circ}{A}$$ comes under :
When an electron jumps from higher orbit to the second orbit in hydrogen, the radiation emitted out will be in $$(R=1.09\times 10^{7}m^{-1})$$
There are only three hydrogen atoms in a discharge tube. The analysis of spectrum shows that in all the hydrogen atoms, electrons are de-exciting from the fourth orbit. What should be the maximum number of spectral lines?
The first line of the sharp series of atomic cesium is a doublet with wavelengths $$1358.8$$ and $$1469.5\,nm$$. Find the frequency intervals (in rad/s units) between the components of the sequent lines of that series.
An atom possessing the total angular momentum $$h\sqrt{6} $$ is in the state with spin quantum number $$S = 1$$. In the corresponding vector model the angle between the spin momentum and the total angular momentum is $$ \theta = 73.2^{\circ} $$. Write the spectral symbol for the term of that state.
