It seems like there's a bit of misunderstanding in the question. Wavelength itself doesn't "travel" through air. Here's why:

* Wavelength: Wavelength is the distance between two successive crests or troughs of a wave. It's a property of the wave, not something that moves.

* What travels: It's the wave itself that travels through air. Waves are disturbances that carry energy, and they can travel through different mediums like air, water, or solids.

Examples:

* Sound waves: These are vibrations that travel through air. The wavelength of a sound wave determines its pitch (high or low).

* Light waves: These are electromagnetic waves that also travel through air. The wavelength of light determines its color.

So, to answer your question more accurately:

Waves with certain wavelengths can travel through air.
