The frequency of strong yellow light in the spectrum of sodium is `5. 09 xx 10 ^(14) s ^(-1).` Calculate the wavelengh of the light.

Explanation

We are given that
Frequency of strong yellow light `=5. 09 xx 10 ^(14) s^ (-1)`
We are to calculate the wavelength of light.
We know that
Wavelength , `lamda = (c)/(v) = (3 xx 10 ^(8) ms ^(-1))/( 5. 09 xx 10^( 14) s ^(-1)) = 0.006 xx 10 ^(-4) m`
