Challenge Problems
Push your limits with advanced challenges
A building is subjected to strong winds creating vibrations. Use the wave equation to model the expected displacement at the top of the building over time, given an initial displacement of 0.5 meters and a wave speed of 1.5 m/s.
💡 Hint: Consider initial conditions for displacement and relate them to wave functions.
Analyze how changing the medium (e.g., from air to water) affects the wave speed of sound. Use the wave equation to substantiate your explanation.
💡 Hint: Think about how sound travels more efficiently in water than in air.
