Question

from the given figure, calculate angle of reflection of
angle of reflection of sound​

Answer 1

Answer 2

$\huge{\boxed {\mathfrak \pink {\fcolorbox {red}{blue}{AnSwEr}}}}$

Angle of incidence = Angle of reflection

90° - 50° = Angle of incidence = Angle of reflection

Angle of incidence = Angle of reflection = 40°
