<u>Given:</u>
Radiation emission in Cs atom = 9,192,632,770 cycles
<u>To determine:</u>
The wavelength of the above radiation
<u>Explanation:</u>
It is given that :-
1 sec equivalent to 9,192, 631, 770
Now, frequency (ν) = cycles /sec = 9,192, 631, 770/sec
Wavelength of a radiation is given as:
λ = c/ν
where c = speed of light = 3*10⁸ m/s
λ = 3*10⁸ ms⁻¹/9,192, 631, 770 s⁻¹ = 0.0326 m
Ans: Thus the wavelength of this radiation is 0.033 m
