An atom is in its excited state ,Does the probability of its coming to ground state depend on whether the radiation is already present or not? If you does it also depends on the wavelength of the radiation present?

An electron changes its position from orbit n=2 to the orbit n=3 of an atom. The wavelength of the emitted radiations is

Does the stopping potential in photoelectric emission depend upon the frequency of the incident radiation?

Mass of a particle depends on its speed . Does the attraction of the earth on the particle also depend on the paricle's speed ?

The ionization energy of the electron in the hydrogen atom in its ground state is 13.6 eV. The atoms are excited to higher energy levels to emit radiations of 6 wavelengths. Maximum wavelength of emitted radiation corresponds to the transition between

The weight of a body at the poles is greater than the weight at the equator. Is it the actual weight or the apparent weight we are talking about? Does your answer depend on whether only the earth's rotation is taken into account or the flattening of the earth at the poles is also taken into account?

Does the force on a charge due to another charge depend on the charges present nearby?

A parallel beam of light of wavelength 100 nm passes through a sample of atomic hydrogengas in ground state (a)Assume that when a photon suppose some of its energy to a hydrogen atom the rest of the energy appears as another photon moving in the same direction as the incident photon Neglecting the light emitted by the excited hydrogen ato in the direction of the incident beam, ? (b) A radiation detector is placed near the gas to detect radiation coming perpenducular to the incident beam find the wevelength of radiation that may be detected by the detector

According to Maxwell's theory of electrodynamics, an electron going in a circle should emit radiation of frequency equal to the frequency of revolution what should be the wavelength of the radiation emitted by a hydrogen atom in ground state if this rule is followed?

Does the stopping potential in photoelectric emission depend upon the intensity of the incident radiation in a photocell ?

Find the wavelength present in the radiation emitted when hydrogen atoms emitted to n = 3 states return to their ground state.
