Hi Tinaaaaaa, welcome to PFTinaaaaaa said:If a sound wave hits multiple scatterers spaced closer than the wavelength and moving fast
but at different velocities how is the reflective beam is affected?
Hi I think I made a mistake. I think i meant it for undergraduate level education.davenn said:Hi Tinaaaaaa, welcome to PF
You have marked your thread with an A tag for post graduate level education
So what research have you done so far on your question ?
So some links to the subject material that you have read and what parts of it you do not understand
Then hopefully people here will be able to help you

The size between scatterers affects reflection by determining the amount and direction of scattering that occurs. If the scatterers are small compared to the wavelength of the incoming wave, the scattering will be isotropic, meaning it will scatter in all directions equally. However, if the scatterers are larger, they may cause more directional scattering, resulting in a change in the reflected wave's amplitude and phase.
The size of scatterers can affect the reflected wave in several ways. First, it can change the intensity or amplitude of the reflected wave. It can also change the direction or angle of the reflected wave. Additionally, the size of scatterers can affect the polarization of the reflected wave, meaning it can change the orientation of the electric and magnetic fields in the wave.
The distance between scatterers can impact reflection by changing the overall scattering pattern. When the distance between scatterers is small, the scatterers can interact with each other, causing interference effects that can alter the reflected wave's characteristics. However, if the distance between scatterers is large, the individual scatterers may act independently, resulting in a different scattering pattern.
Yes, the shape of the scatterers can impact reflection. Different shapes can cause different scattering patterns, resulting in variations in the reflected wave's intensity, direction, and polarization. For example, a spherical scatterer may produce a different scattering pattern than a cylindrical scatterer, even if they are the same size and distance apart.
The material of the scatterers can affect reflection by influencing the absorption and scattering properties. Some materials may absorb more of the incoming wave, resulting in a weaker reflected wave. Others may scatter the wave more efficiently, causing a change in the reflected wave's direction or polarization. Additionally, the refractive index of the material can also impact the reflected wave's phase and amplitude.
