Answer #1

9. (D) stimulated emission, is correct option.

10. (H) a converging lens, is correct option.

Because laser produces coherent light through a process known as STIMULATED EMISSION. You may know that light is the result of spontaneous emission of a photon by an electron undergoing a transition in an atom.
