Characteristics of the medium required for the propagation of sound

Which of the following is not a medium for sound waves?

in which medium does sound travel faster.

Q4.Answer the following1. A transverse wave travels along the x-axis. The particles of the medium must move in Whichdirection?2. Sound waves from a point source are propagating in all directions. What will be the ratio ofamplitudes at distances of x meter and y meter from the Source?3. What is a harmonic Wave function?4. Which properties of the medium are responsible for propagation of Waves through it?5. What is the nature of the thermal change in air, when a sound wave propagates through it?6. Why does sound travel faster in iron than in Water or air?7. Under what conditions does a sudden phase reversal of Waves on reflection take place?8. The speed of sound does not depend upon its frequency. Give an example in support of thisstatement.

Sound is transmitted through gases, plasma, and liquids as....

Which statement below is true?Sound waves are longitudinal waves and they propagate parallel to the transmitting medium.Sound waves are transverse waves and they propagate perpendicular to the transmitting medium.Sound waves can propagate as longitudinal or transverse waves, depending on the temperature and humiditySound waves can propagate as longitudinal or transverse waves, depending on the transmitting medium
