When a hydrogen atom going from "n=2" to "n=1" emits a photon,its recoil speed is `(x)/(5)`m/s .Where "x=_________________" (Use,mass of hydrogen atom `=1.6times10^(-27)kg)`

When a hydrogen atom emits a photon in going from n=5 to n=1, its recoil speed is almost

When a photon is emited by a hydrogen atom , the photon carries a momentum with it (a) calculate the momentum carreied by the photon when a hydrogen atom emits light of wavelength 656.3 nm (b) with what speed does the atoms recoil during this transition? Take the mass of the hydrogen atom = 1.67 xx 10^(-27) kg (c ) Find the kinetic energy of recoil of the atom

A hydrogen atom a photon corresponding to an electron transition from n=5 to n=1 .The recoil speed of hydrogen atom is almost (mass of proton 1.6times10^(-27)kg) (A) 10m/s (B) 2times10^(-2)m/s (C) 4m/s

If an electron of a hydrogen atom jumps from n = 2 to n=1 then find the wavelength of released photon

The recoil speed of a hydrogen atom after it emits a photon is going form n=5 state to n =1 state is ….. m/s.

A hydrogen atom moving at a speed v absorbs a photon of wavelength 122 nm and stops. The value of v is (mass of hydrogen atom =1.67xx10^(-27) kg)

A hydrogen atom emits a photon corresponding to an electron transition from n = 5 to n = 1 . The recoil speed of hydrogen atom is almost (mass of proton ~~1.6 xx 10^(-27) kg) .
