In gamma ray emission form a nucleus

The half life time of a radioactive elements of x is the same as the mean life of another radioactive element Y. Initially they have same number of atoms, then

which of the following transition in hydrogen atoms emits Photon of highest frequency?

An electron Passing through a Potential difference of 4.9 v collides with a mercury atom and transfer it to the first excited state what is transfer it to the first excited state. what is the wave length of Photon corresponding to the fraction of mercury atom to its normal state.

The binding energy per nucleon for the Parent nucleus is E₁ and that for the daughter nuclei is E₂ then

The speed of daughter nuclei is
