हिन्दीThe frequency of electromagnetic radiation having a wavelength of \( 5800\text{ \AA} \) is approximately:
Correct answer · Option 2
\( 5.17 \times 10^{14}\text{ s}^{-1} \)
Explanation
Using frequency \( \nu = \frac{c}{\lambda} = \frac{3 \times 10^8\text{ m s}^{-1}}{5800 \times 10^{-10}\text{ m}} = 5.17 \times 10^{14}\text{ s}^{-1} \).
