Question

If angle between incident sound wave and reflected sound wave is 125ᴼ, then angle of reflection is
a. 125ᴼ b. 150ᴼ c. 40ᴼ d. 90ᴼ

Answer 1

Hi there !!

Angle of incidence = Angle of reflection

Given :-

Angle of incidence +Angle of reflection = 125 ᴼ

Angle of reflection = Angle of incidence 

2 Angle of reflection = 125ᴼ

Angle of reflection = 125/2
                             = 62.5 ᴼ

Answer 2

Angle of incidence= Angle of reflection
Angle of incidence+Angle of reflection= 125°
2 Angle of Incidence= 125°
Angle of Incidence= 125°/2
= 62.5°
Angle of Incidence= Angle of reflection= 62.5°

Hope this helps you...
plz mark it as a brainliest answer...
