Nitrogen laser produces a radiation at a wavelength of 337.1 nm. If the number of photons emitted is `5.6 xx 10^(24).` Calculate the power of this laser.

Explanation

To calculate the power of the nitrogen laser, we can follow these steps:

### Step 1: Understand the formula for power
The power \( E \) of the laser can be calculated using the formula:
\[ E = \frac{n \cdot h \cdot c}{\lambda} \]
where:
