Answer: Your welcome!
Step-by-step explanation:
a.) The normalized wavefunction is ψ(φ) = (1/2π)e iφ. This wavefunction satisfies the normalization condition:
∫ 0 2π |ψ(φ)|2 dφ = 1
b.) The probability of finding the light atom in the volume element dφ at φ = π is (1/2π)|e iπ|2 = 1/2π. This is because the absolute value squared of the wavefunction |ψ(φ)|2 = (1/2π)2, and the integral of the wavefunction over the entire domain is equal to 1. Therefore, the probability of finding the light atom in the volume element dφ at φ = π is (1/2π)|e iπ|2 = 1/2π.
