When a hydrogen atom is excited from ground state to first excited state then

Hydrogen atom in its ground state is excited by means of a monochromatic radiation of wavelength 970.6 Å . Different wavelengths are possible in the spectrum. After absorbing the energy of radiation, hydrogen atom goes to the excited state. After 10^(-8) s, the hydrogen atom will come to the ground state by emitting the absorbed energy.
