A hydrogen atom absorbs a photon radiation causing an electron to jump from level one to level two. If the photon/radiation has a wavelength of 5.62 x 10^-3 m to calculate the frequency of the radiation absorbed and the energy change of the electron

1.  

First of all, let's convert the energy of the absorbed photon into Joules:

The energy of the photon can be rewritten as:

where

h is the Planck constant

c is the speed of light

is the wavelength of the photon

Re-arranging the formula, we can solve to find the wavelength of the absorbed photon:

2. 1.24 eV

In this case, when the electron jumps from the n=4 level to the n=3 level, emits a photon with wavelength

So the energy of the emitted photon is given by the formula used previously:

and using

we find

converting into electronvolts,

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
