Challenge Problems
Push your limits with advanced challenges
Design a sound system that prioritizes sound quality. Discuss how each characteristic of sound waves—amplitude, frequency, wavelength, and speed—plays a role in your design choices.
💡 Hint: Consider environments like concert halls or home theaters.
A sound has a frequency of 1000 Hz and travels through air at 343 m/s. Calculate its wavelength. If it were to travel through water at 1482 m/s, what would the new frequency be?
💡 Hint: Use the relationships v = f × λ for both air and water.
