हिन्दीWhat is the wavenumber of yellow radiation having a wavelength of \( 5800\text{ \AA} \)?
Correct answer · Option A
\( 1.724 \times 10^4\text{ cm}^{-1} \)
Explanation
Wavenumber \( \bar{\nu} = \frac{1}{\lambda} = \frac{1}{5800 \times 10^{-10}\text{ m}} = 1.724 \times 10^6\text{ m}^{-1} = 1.724 \times 10^4\text{ cm}^{-1} \).
