AI Thread Summary
The discussion focuses on determining the fundamental frequency of the human ear, modeled as a closed-end tube approximately 2.8 cm long. Using the speed of sound at 340 m/s, the relationship between wave speed, frequency, and wavelength is explored. The fundamental frequency can be calculated by considering the wavelength for a tube closed at one end, which is four times the length of the tube. Participants express confusion about the calculations and seek clarification on how to derive the frequency from the given dimensions. Understanding this fundamental frequency is crucial for insights into human ear sensitivity.

The human ear canal is about 2.8 cm long, if it is regarded as a tube that is open at one end and closed at the eardrum, what is the fundamental freq. around which we would expect hearing to be most sensitive? Take the speed of sound to be 340 m/s.

Is it:

wave speed = frequency x wave length

340 = f x 2.8 etc.? Not real sure. Thanks for any help in advance.

Think about the wavelength of the fundamental if the tube is closed at one end and it is 2.8cm long.
 
sorry not really getting you.. :confused:

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
