A string is sustaining a stationary wave when

Jamb 1978

A string is sustaining a stationary wave when A. the frequency of the wave is hot proportional to the wavelength of the wave B. the amplitude of vibration is always zero C. two equal waves are travelling in opposite directions D. the waves are longitudinal E. the frequency is directly proportional to the length of the string.

ANSWER: Option C

EXPLANATION: Stationary waves are formed by the superposition of two traveling waves of the same frequency (with the same polarization and the same amplitude) traveling in opposite directions. This is usually achieved by using a traveling wave and its reflection, which will ensure that the frequency is exactly the same.
