The wavelength of a photon is 1.4 Å. It collides with an electron. The energy of the scattered electron is `4.26xx10^(-16)` J. Find the wavelength of photon after collision.

Explanation

To solve the problem, we need to find the wavelength of the photon after it collides with an electron. We will use the energy of the scattered electron and the initial wavelength of the photon to find the final wavelength.

### Step-by-Step Solution:

1. **Identify Given Values:**
- Initial wavelength of the photon, \( \lambda_1 = 1.4 \, \text{Å} = 1.4 \times 10^{-10} \, \text{m} \)
- Energy of the scattered electron, \( E = 4.26 \times 10^{-16} \, \text{J} \)
