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

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 radiation of 6 wavelengths. During which of the following transitions will the maximum wavelength radiation be emitted ?

Obtain the frequency of revolution of the electron in its circular orbit. Does the answer depend on the speed of the electron? Explain.

To excite the hydrogen atom from its ground state to second excited state…. eV energy is required.

An electron in hydrogen atom first jumps from second excited state to first excited state and then from first excited state to ground state. Let the ratio of wavelength, momentum and energy of photons emitted in these two cases be a, b and c respectively, Then

An electron collides with a fixed hydrogen atom in its ground state. Hydrogen atom gets excited and the colliding electron loses all its kinetic energy. Consequently the hydrogen atom may emits a photon corresponding to the largest wavelength of the Balmer series. The K.E. of colliding electron will be..

The first excited state of hydrogen atom is 10.2 eV above its ground state. The temperature is needed to excite hydrogen atoms to first excited level is

How does the resistance of a metallic Wire depend on its temperature?

Hydrogen atom from excited state comes to the ground state by emitting a photon of wavelength lamda , then what is the quantum number of excited states ?
