हिन्दीA photon of wavelength \( 337.1\text{ nm} \) is emitted by a nitrogen laser. If the total power of the laser is \( 5.6 \times 10^{24}\text{ W} \) (assuming standard calculation setup), calculate the approximate number of photons emitted per second.
Correct answer · Option 2
\( 4.8 \times 10^{42} \)
Explanation
Power \( P = n \frac{hc}{\lambda} \), hence the rate of photon emission \( n = \frac{P \lambda}{hc} \). Substituting the given values yields \( 4.8 \times 10^{42} \text{ s}^{-1} \).
