What is meant by resonance? The ear canal can be thought of as a pipe open at one end.
Worked Solution & Example Answer:What is meant by resonance? The ear canal can be thought of as a pipe open at one end. - Leaving Cert Physics - Question vi - 2022
Step 1
Step 2
Draw a labelled diagram to show the first position of resonance for a sound wave in a pipe open at one end.
Answer
The diagram should illustrate a pipe open at one end. The closed end has a node (point of no displacement), while the open end features an anti-node (point of maximum displacement). Label these parts clearly.
Step 3
The frequency of a sound wave is 2800 Hz and it has a wavelength of 0.12 m. Calculate the speed of the wave.
Answer
To calculate the speed of the wave, use the formula:
ho$$ Where: - $v$ = speed of the wave - $f$ = frequency (2800 Hz) - $\rho$ = wavelength (0.12 m) Thus, $$v = 2800 imes 0.12 = 336 \, \text{m/s}$$
