The shortest wavelength for audible sound depends on the upper limit of the human hearing range and the speed of sound.

• The upper frequency limit for human hearing is typically around 20,000 Hz (20 kHz).
• The speed of sound in air is approximately 343 meters per second.

Using the formula Wavelength=Speed of Sound/Frequency

Wavelength = 343 m/s /20,000 Hz

Wavelength = 0.01715 meters

=1.715 cm

So, the shortest wavelength for audible sound is approximately 1.715 centimeters.
