1.	Two simple harmonic waves of the same amplitude and frequency, but 90° out of phase, pass through the same region in a medium. The resultant wave has (A) an amplitude greater than either of the component waves (B) an amplitude smaller than either of the component waves (C) zero amplitude (D) an amplitude slowly varying with time.
Answer» (A) an amplitude greater than either of the component waves
