Calculate the wavelength of yellow light produced by a sodium lamp if the frequency of radiation is 3.34 x 10^14 Hz

max2010maxim [7]

Answer : The wavelength of yellow light produced by a sodium lamp is, $8.98\times 10^{-7}m$

Explanation : Given,

Frequency of radiation = $3.34\times 10^{14}Hz=3.34\times 10^{14}s^{-1}$

conversion used : $Hz=s^{-1}$

Formula used :

$\nu=\frac{c}{\lambda}$

where,

$\nu$ = frequency of radiation

$\lambda$ = wavelength of radiation

c = speed of light = $3\times 10^8m/s$

Now put all the given values in the above formula, we get:

$3.34\times 10^{14}s^{-1}=\frac{3\times 10^8m/s}{\lambda}$

$\lambda=8.98\times 10^{-7}m$

Therefore, the wavelength of yellow light produced by a sodium lamp is, $8.98\times 10^{-7}m$
