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

Sagot :

Answer:

[tex]\lambda=5.70\times 10^{-7}\ m[/tex]

Explanation:

The frequency of a sodium vapor lamp, [tex]f=5.26\times 10^{14}\ Hz[/tex]

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

[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{5.26\times 10^{14}}\\\\\lambda=5.70\times 10^{-7}\ m[/tex]

So, the wavelength of light is equal to [tex]5.70\times 10^{-7}\ m[/tex].
