Challenge Problems
Push your limits with advanced challenges
A string on a musical instrument vibrates at a frequency of 440 Hz, producing sound. If the tension of the string is increased, causing the frequency to rise to 880 Hz, what happens to the wavelength if the speed of sound in the medium remains constant?
💡 Hint: Think about the relationship between speed, frequency, and wavelength.
Analyze how changing the medium from water to air affects the speed of sound and frequency of a wave, while maintaining the same energy input. Explain your reasoning.
💡 Hint: Refer to the properties of sound in different media.
