Sound waves are mechanical waves in which the particles in the medium vibrate in a direction parallel to the direction of energy transport. what is another name for the type of wave that transfers energy in this way?

question 4 options:

a. longitudinal waves

b. transverse waves

c. pressure waves

d. surface waves

a. Longitudinal waves

Explanation:

Waves can be classified into two different types:

- Transverse waves: in transverse waves, the vibration of the medium occurs in a direction perpendicular to the direction of propagation of the wave. An example of transverse waves are electromagnetic waves.

- Longitudinal waves: in longitudinal waves, the vibration of the medium occurs in a direction parallel to the direction of propagation of the wave. Sound waves are examples of longitudinal waves, because they are produced by the motion of the air particles (or of the particles of the medium) which oscillate back and forth along the direction of propagation of the wave.

Therefore, the correct answer is

a. Longitudinal waves

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

not too sure thinking all accelerations are pointed down
