The diagram shows the standing wave pattern of a vibrating string which is fixed at ends X and Y.
Which one of these statements is true?
P to R is one wavelength.

period
What is the Doppler effect?
When a wave meets and interferes with its own reflection
When a wave is shifted when a body pushes the wave
The change in frequency due to the motion of the wave source or the observer
