A tuba is a instrument that can be modeled after a closed tube and has a length of 4.9m. A frequency of 122.5hz produces resonance in the Tuba. Is this the fundamental frequency of the instrument? If not, what harmonic is it?
4l=λ(open closed tube)
Consider a hypothetical scenario where you are present in an elevator which is either at rest or is moving with constant velocity (ignore cases of acceleration when elevator stops/starts moving). Now how will you determine if the elevator is moving or not given that there are no windows in the...
I'm trying to solve two problems related to standing waves and wave interference; while I'm not having difficulty with the actual solving portion, I don't know if I'm interpreting the questions correctly.
Question 1: "A violin string is tuned to 460 Hz (fundamental frequency). When...
