The frequency of the strong yellow line in the spectrum of sodium in `5.09 xx 10^(14)s^(-1)` .Calculate the wavelength of the light nanometres

Explanation

To calculate the wavelength of the light given the frequency, we can use the formula that relates the speed of light (c), frequency (ν), and wavelength (λ):

\[ c = \nu \cdot \lambda \]

Where:
- \( c \) is the speed of light, approximately \( 3.00 \times 10^8 \) meters per second.
