NEET Chemistry Quantum Mechanical Model MCQ Question
If a nitrogen laser emits radiation at a wavelength of 337.1 nm and the number of photons emitted is 5.6 × 10^24, what is the power of this laser?
11 W
52 W
18 W
5.67 W
Correct Answer
Detailed Explanation
Power can be calculated using the formula P = (Energy of one photon) × (Number of photons) / Time. The energy of one photon can be calculated using E = hc/λ. The given number of photons and wavelength allow us to find energy per photon and thus power.
