The discussion centers on how the size and spacing of scatterers relative to the wavelength of sound waves influence reflection, particularly when scatterers are moving at different velocities. The original poster seeks clarification on the effects of these factors on the reflective beam. Participants encourage the poster to share prior research and specific areas of confusion to facilitate more targeted assistance. There is a correction regarding the educational level of the inquiry, indicating it is intended for undergraduate rather than postgraduate discussion. Overall, the thread emphasizes the importance of understanding the interaction between sound waves and scatterers in acoustic studies.
