An atom absorbs a photon of wavelength 500nm and emits another photon of wavelength 700nm. Find the net energy absorbed by the atom in the process.

Explanation

To find the net energy absorbed by the atom when it absorbs a photon of wavelength 500 nm and emits another photon of wavelength 700 nm, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Wavelengths:**
- Wavelength of the absorbed photon, \( \lambda_a = 500 \, \text{nm} = 500 \times 10^{-9} \, \text{m} \)
- Wavelength of the emitted photon, \( \lambda_e = 700 \, \text{nm} = 700 \times 10^{-9} \, \text{m} \)
