A photon of `3000 Å` is obserbed by a gas and then re-emmited as two photon .One photon in red (`7600 Å)` what would be the wavelength of the other photon ?

Explanation

To solve the problem, we need to apply the principle of conservation of energy, which states that the energy absorbed by the gas must equal the total energy emitted as two photons.

### Step-by-Step Solution:

1. **Understand the Energy of Photons**: The energy of a photon is given by the formula:
\[ E = \frac{hc}{\lambda} \]
