Btwo interfering waves of the same frequency must travel in the same direction
Ctwo interfering waves of the same amplitude must travel at right angles to each other
Dtwo interfering waves of the same amplitude must travel in the same direction

Standing waves can occur in either stationary or moving mediums.In stationary mediums, a standing wave generally occurs as a result of interference between two waves moving in opposite directions, as between a fundemental and its reflection in the closed volume of a resonating chamber such as an organ pipe.

Answer:

A) two interfering waves of the same frequency must travel in opposite directions

Explanation:

In a stationary medium, a standing wave is caused by the interference of two waves of the same nature, that is, with equal amplitude, wavelength and frequency, that move in the opposite direction. The frequency of the resulting wave coincides with that of the waves that generate it.
