Question

If an electron in a hydrogen atom jumps from an orbit of level n=3 to an orbit of level n=2 ,emitted radiation has a frequency

Answer 1

Answer:

when an electron jumps from excited level to ground level it will some energy in the from of radiation, that radiation contains electromagnetic field, it has different waves with different wavelengths and frequencies.

Answer 2

Answer :-

n1 = 1 (Ground Level)

n2 = 3(Excited state)

Rh = Rydberg constant = 10 973 731.6 m-1λ

= wavelength.v

= frequency.

The and formula we will use is

:Putting values :

1/ λ = 10 973 731.6 * (1 - 1/9)1/ λ

= 10 973 731.6 * 8/91/ λ

= 9754428.09λ

= 1.025 * 10^-7

mUsing v * λ

= c (c c= speed of light = 3 * 10^8)

v = c / λv

= 2.92 * 10^15 sec^-1
