A string is sustaining a stationary wave when
...A string is sustaining a stationary wave when
the frequency of the wave is not proportional to the wavelength of the wave
the amplitude of vibration is always zero
two equal waves are travelling in opposite directions
the waves are longitudinal
the frequency is directly proportional to the length of the string
Correct answer is C
-Standing waves are produced on a string when equal waves travel in opposite directions.
-A stretched string is fixed at both ends, when it is plucked at mid point, two reflected waves of same amplitude and frequency at the ends are travelling in opposite direction and overlap along the length. Then the resultant waves are known as the standing waves (or) stationary waves.
