Answer : The wavelength of yellow light produced by a sodium lamp is, 
Explanation : Given,
Frequency of radiation = 
conversion used : 
Formula used :
where,
= frequency of radiation
= wavelength of radiation
c = speed of light = 
Now put all the given values in the above formula, we get:
Therefore, the wavelength of yellow light produced by a sodium lamp is,
