If a sound wave that is traveling in the air
approaches a flat water surface with an angle of incidence of 10.6◦, what is the angle of refraction? Answer in units of ◦.
The laws of refraction and reflection are the same for sound and for light. The speed of sound is 340 m/s in air and 1510 m/s in water. ?

✔ 最佳答案
1: air2: water
sin(θ₁)/sin(θ₂) = v₁/v₂
sin(10.6°)/sin(θ₂) = 340/1510
sin(θ₂) = 1510 sin(10.6°) / 340
θ₂ = sin⁻¹[1510 sin(10.6°) / 340]
Angle of refraction, θ₂ = 54.8°
