Emissions X and Y from radioactive material are sent through a magnetic field. The diagram indicates the direction of the emissions, the direction of the magnetic field and what happens to the emissions. What type of emission is X, and what type of emission is Y?
- Aemission X: $\alpha$-particles; emission Y: $\beta$-particles
- Bemission X: $\alpha$-particles; emission Y: $\gamma$-rays
- Cemission X: $\beta$-particles; emission Y: $\alpha$-particles
- Demission X: $\beta$-particles; emission Y: $\gamma$-rays
