If the propagation speed of Medium 1 is less than the propagation velocity of Medium 2, the transmitted sound beam angle at the interface will: equal the incident beam angle refract towards normal incidence refract away from normal incidence

What can we say about the transmitted sound beam for two adjacent media (specular interface) that have the same sound velocities? The transmitted angle is less than the incident angle The transmitted angle is refracted toward normal incidence The transmitted angle is the same as the incident angle The reflected angle is different than the incident angle

Suppose that the propagation velocity of Medium 2 is 1300 m / sec and the propagation velocity of Medium 1 is 1200 m / sec. For an incident angle is 30°, is the refracted angle toward or away from normal? toward no refraction occurs away from

Of the following choices, refraction requires which of the following factors? media velocity differences medium 1 velocity > medium 2 velocity acoustic impedance differences perpendicular incidence

Characteristics of the medium required for the propagation of sound

Sound wave is incident on Air water interface. If equation of incident disturbance at interface is S = S0 sin (ωt). Here V and B are speed of sound and Bulk modulus respectively.If 2B2V1 = B1V2, amplitude of reflected disturbance will be .If 2B2V1 = B1V2, amplitude of transmitted disturbance will be .If B2V1 = 2B1V2, amplitude of reflected disturbance will .If B2V1 = 2B1V2, then amplitude of transmitted disturbance will be
