Wavelength of sound app for iPhone and iPad

Do you know the wavelength of sound? Sound (sound) is a sound wave generated by the vibration of an object. It is a wave phenomenon that is transmitted through the medium (air or solid, liquid) and can be perceived by human or animal hearing organs. The object that originally vibrates (vibrates) is called the sound source. Sound travels in the form of waves (vibrations). Sound is the movement of sound waves through any medium.
As a wave, sound with a frequency between 20 Hz and 20 kHz can be recognized by the human ear.
This is a tool to help you quickly calculate the wavelength of sound.
