Aground state hydrogen atom absorbs a photon of wavelength 94.98 nm and its electron attains a higher energy level. the atom then emits two photons: one of wavelength 1282.2 nm to reach an intermediate level and a second to return to the ground state. what was the wavelength of the second photon emitted?

102.63 nm

Explanation: In order to explain this problem we have to considerer the Plack postulate for the energy of the photons given by:

E=h*c/λ where H and c are the Planck constant and speed of light.

E=1240 nm*eV/94.98 nm= 13.05 eV

Then we have a first emitted photon with a wavelength of 1282.2 nm so  its energy is;

Einter=1240/1282.2=0.97 eV

so the energy to get the ground state from this level is

E=(13.05-0.97)=12.08 eV

From this level, the second  emitted photon has a wavelength given by:

λ=1240/12.08=102.65 nm

unbalanced force

explanation:

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
