Answer :
Final answer:
When the ear canal is full of water, the first resonant frequency increases due to the greater speed of sound in water compared to air. The resonant frequency is related to the material the tube is filled with and the speed of sound in that material.
Explanation:
The first resonant frequency of the ear canal, or any tube-like structure, is influenced by the substance it is filled with. When filled with air, the ear canal resonates at its fundamental or first frequency. If the canal is full of water, the speed of sound and hence the resonant frequencies would increase. This is because the speed of sound in water is faster than in air.
The resonance of a tube is related to its length and the speed of the sound in the filled material. In terms of the ear canal, the first resonant frequency, also known as the fundamental frequency, would be higher when the canal is full of water. This is due to the increased speed of sound in water compared to air.
Recall that for a tube open at both ends, like the ear canal, the fundamental wavelength (associated with the first resonant frequency) of the tube is defined as 2L, where L is the length of the tube. Given that the speed of sound is a factor in calculating frequency (frequency = speed/wavelength), a greater speed of sound in water translates to higher frequencies, including the first resonant frequency, when compared to the frequencies in air.

Final answer:
The first resonant frequency in the ear canal would decrease if the canal is full of water due to the higher speed of sound in water compared to air. This affects sound perception because the natural amplification provided by the ear canal's resonance would shift to lower frequencies.
Explanation:
When the ear canal is full of water, the first resonant frequency changes significantly due to the difference in the speed of sound in air versus water. Normally, the ear canal resonates like a tube closed at one end, with air conveying the sound waves. However, if filled with water, the speed of sound is higher, and thus the wavelength of the sound will be longer.
The fundamental frequency of a resonating tube is inversely proportional to the wavelength, so when the ear canal is filled with water, the wavelength increases, and the fundamental frequency decreases. This means the first resonant frequency will be lower than when the ear canal contains air.
The correlation of this to the intensity versus frequency graph of the human ear shows the sensitivity to various frequencies. As the resonant frequency shifts downwards, certain frequencies may not be amplified as effectively by the ear canal's resonance, which could affect how we perceive sounds when the ear canal is filled with water, as it happens when swimming or bathing.
