Question

A sodium vapor lamp omit waves with the frequency of 5.26x10^14 Hz. What is the wavelength of light?

Answer 1

`\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`.
