Onde progressive</span>.<br> Dans une cuve remplie d'eau, on dispose à une extrémité deux haut-parleurs qui sont reliés à un générateur de fonctions et qui émettent simultanément une impulsion sonore. De l'autre côté de la cuve, on place deux récepteurs, l'un dans l'air, l'autre dans l'eau. Les récepteurs sont à une distance D = 3,0 m des émetteurs et sont reliés à un oscilloscope dont l'oscillogramme est donné ci-dessous.<br> <img style="width: 535px; height: 350px;" alt="" src="image/fesic1.jpg"><br> Données : vitesse du son dans l'air ~ 3 x l0<sup>2</sup>m.s<sup>-1</sup> ; vitesse du son dans l'eau ~1,5 km.s<sup>-1</sup>.<br> <span style="font-weight: bold;">a)</span> Une onde sonore est une onde mécanique transversale.
