Challenge Problems
Push your limits with challenges.
Question 1
A sound wave travels through various mediums: air (343 m/s), water (1482 m/s), and steel (5000 m/s). If it takes 2 seconds to travel a distance of 2000 meters in steel, what is the delay when traveling the same distance in air?
💡 Hint: Use the speed formula to find time in each medium.
Question 2
If the temperature in air increases from 20°C to 40°C, calculate the new speed of sound. Using the formula v = 331 + 0.6*T, what would the new speed be?
💡 Hint: Substitute the new temperature into the speed formula.
