B. travels at the same speed through a given medium.

C. has the same wavelength.

D. moves with the same amplitude.

  • A. travels with decreasing amount of energy through a given medium. That is why sound is not heard if the distance is long.

    B. travels at the same speed through a given medium. Speed depends on the density and elastic property of the medium and since these properties do not change except with temperature, speed remains the same generally.

    C. has the same wavelength. Since frequency and speed is the same in a given medium wavelength also remains the same

    D. moves with decreasing amount of amplitude. The energy depends on the amplitude. Both amplitude and energy decreases with distance traveled.

  • B. travels at the same speed through a given medium.

    Speed depends on medium, nothing else. For example, a high-pitch sound and a low-pitch sound travels at the same speed of sound through air.
