Will surface roughness alters reflected sound energy?
. Surface roughness reflected sound energy.
First Law:
The angle of incidence is to angle of reflection of the sound wave.
The angle of incidence is to angle of reflection of the sound wave.
Second Law:
The incident sound wave, the to the point of incidence, and the sound wave all lie in the .
