`A` near ultra violet photon of wavelength `300nm` is absorbed by a gas and then emitted as two photons. One photons is of red light with wavelength `760nm`. What would be the wave length of the second photon?

Explanation

To solve the problem, we will use the concept of energy conservation in photon emission. The energy of the absorbed photon is equal to the sum of the energies of the emitted photons.

### Step-by-Step Solution:

1. **Identify the given values:**
- Wavelength of the absorbed photon, \( \lambda = 300 \, \text{nm} \)
- Wavelength of the first emitted photon (red light), \( \lambda_1 = 760 \, \text{nm} \)
- Wavelength of the second emitted photon, \( \lambda_2 \) (unknown)
