To solve the problem of calculating the wavelengths corresponding to the gamma emission when a positron and an electron collide and annihilate, we can follow these steps: ### Step 1: Understand the Energy Released When an electron (mass \( m_e = 9.1 \times 10^{-31} \) kg) and a positron collide, they annihilate each other, resulting in the release of energy in the form of gamma photons. The total energy released can be calculated using Einstein's equation: \[ E = mc^2 \] ...
