is a constant. When the frequency goes up, the wavelength comes down. Wavelength goes up, frequency goes down. So, if we have a wave here -- over here, that's what's interesting -- as the pitch goes up, things get closer, pitch goes down, things stretch out.
este o constanta.Cand frecventa creste, lungimea de unda coboara. Lungimea de unda creste, frecventa coboara. Deci daca avem aici o unda-- aici, asta e intresant-- Cand frecventa urca,lucrurile se apropie, frecventa coboara,lucrurile se departeaza.
