Question

which of the following is the requirement for rgular reflection of sound​

Answer 1

Answer:

Sound waves are much longer than light waves so they require a much larger area of reflection. 1)The incident,reflected sound wave and normal at the point of incidence,all lie in same plane. 2)The angle of reflection of sound is always equal to angle of incidence of sound.

Answer 2

Answer:

Sound waves are much longer than light waves so they require a much larger area of reflection.

1)The incident,reflected sound wave and normal at the point of incidence,all lie in same plane.

2)The angle of reflection of sound is always equal to angle of incidence of sound.
