A small amount of magnetic-field splitting of spectral lines occurs even when the atoms are not in a magnetic field. What causes this?
This is due to spin orbit coupling.

Most black-and-white photographic film (with the exception of some special-purpose films) is less sensitive to red light than blue light and has almost no sensitivity to infrared. How can these properties be understood on the basis of photons?
A photon of frequency fundergoes Compton scattering from an electron at rest and scatters through an angle . The frequency of the scattered photon is f'. How is f' related to f? Does your answer depend on ? Explain.
Compared to particles with the same energy, particles can much more easily penetrate through matter. Why is this?
Assume that the universe has an edge. Placing yourself at that edge in a thought experiment, explain why this assumption violates the cosmological principle.
In the process of internal conversion, a nucleus decays from an excited state to a ground state by giving the excitation energy directly to an atomic electron rather than emitting a gamma-ray photon. Why can this process also produce ray photons?
