Question

a student while verifying the laws of reflection of sound measured the angle between incident sound wave and reflected sound wave is 110 degree. calculate the angle of reflection.

Answer 1

110/2
55
bcoz angle of reflection = angle of incidence

hope it helps you mate!!

Answer 2

As given ∠ incidence + ∠ reflection of sound with respect to medium is 110°

so, as per law of reflection of sound

∠incidence is equal to ∠ reflection

so

∠ incidence + ∠ reflection =110°

∠ reflection + ∠ reflection  = 110°

2 ∠reflection = 110°

∠ reflection = 110°/2

∠ reflection = 55°

hope it helps
