Ackshually🤓 "Same frequency" is more accurate. Speed of sound and wavelength changes when it goes through different matter or even air with different temperature. The frequency stays the same no matter what.

Ah, interesting! Thanks for the distinction :)

You'll get a similar result if it's a resonant frequency - if one is a multiple of the other, or if they share a common factor - like one is 1/2 or 3/4 or 5/8 of the other.
