Question

A) A molecule (that is 10x larger than an electron) is at rest

until it is hit by an x-ray phototon (λ=500nm). After the impact,
the photom leaves at 150.0o from its initial direction.
What would be

Answer 1

the recoil angle of the molecule?

The recoil angle of the molecule will depend on the magnitude of the momentum of the photon and the mass of the molecule. We can use conservation of momentum to calculate the recoil angle, which is given by the equation: θ = 2 tan^-1 (p/2mv). Thus, the recoil angle of the molecule can be determined once the momentum of the photon and the mass of the molecule are known.
