Challenge Problems
Push your limits with challenges.
Question 1
A sound wave passing from air (speed = 343 m/s) into water (speed = 1482 m/s) strikes the water surface at an angle of 30 degrees. Using Snell’s Law, find the angle of refraction in water.
💡 Hint: Remember to convert speeds into indexes of refraction!
Question 2
Critically evaluate how sound refraction would differ in a situation combining changing temperature, such as sound traveling through hot air to cooler water and its practical implications.
💡 Hint: Consider how changes in relative density and temperature interact.
