Question

two speakers are located in the same room filled with air. both play sounds with the same pitch. the sound from one speaker is louder than the other. which wave properties are the same for the two sounds? choose 3 answers: a speed b amplitude c frequency d wavelength

Explanation:

1. Speed: Sound speed in a medium (air here) depends on medium properties, so same for both sounds.
2. Frequency: Pitch is related to frequency; same pitch means same frequency.
3. Wavelength: Using \( v = f\lambda \) ( \( v \) speed, \( f \) frequency, \( \lambda \) wavelength), if \( v \) and \( f \) are same, \( \lambda \) is same.

Amplitude relates to loudness (louder means larger amplitude), so amplitude differs.

Answer:

A. speed, C. frequency, D. wavelength
