Answer:

$\lambda=5.70* 10^(-7)\ m$

Step-by-step explanation:

The frequency of a sodium vapor lamp,
$f=5.26* 10^(14)\ Hz$

We need to find the wavelength of light. The relation between wavelength, frequency and speed of light is given by :

$c=f\lambda\\\\\lambda=(c)/(f)\\\\\lambda=(3* 10^8)/(5.26* 10^(14))\\\\\lambda=5.70* 10^(-7)\ m$

So, the wavelength of light is equal to
$5.70* 10^(-7)\ m$ .
