What is the longest wavelength that can be heard by a normal ear?

Fl = 20 Hz = Lowest Freq.

L = V/F = 340m/s / 20 c/s = 17 m.

The longest wavelength that can be heard by a normal human ear is approximately 17 meters, corresponding to a frequency of about 20 Hz. Frequencies below this range are typically felt as vibrations rather than heard as sound. It's worth mentioning that humans' ability to perceive sound can vary, and age can also affect the range of audible frequencies.

The normal human ear can perceive sound within a range of frequencies, from about 20 Hz to 20,000 Hz. The longest wavelength that can be heard by a normal ear corresponds to the lowest frequency that can be perceived, which is about 20 Hz.

To understand the relationship between wavelength and frequency, you can use the formula:
Wavelength = Speed of Sound / Frequency

The speed of sound in air is approximately 343 meters per second at room temperature. Plugging in the frequency of 20 Hz into the formula, we can calculate the corresponding wavelength:
Wavelength = 343 m/s / 20 Hz ≈ 17.15 meters

Therefore, the longest wavelength that can be heard by a normal ear is around 17.15 meters.
