Heya Friend ✋✋✋
Angle of incidence = Angle of reflection...
Angle of incidence = 50°
so angle of reflection = 50°
The angle between incident and reflected sound wave = angle of incidence + angle of reflection...
= 50° + 50°
= 100°
Angle of incidence = Angle of reflection...
Angle of incidence = 50°
so angle of reflection = 50°
The angle between incident and reflected sound wave = angle of incidence + angle of reflection...
= 50° + 50°
= 100°

Answer:
80 degree
Explanation:
Angle of incidence = 90 -50
=40 degree
Therefore Angle of reflection = 40degree
The angle they form = 40+40
= 80 degree
