D
Sound Waves
Sound and water waves are mechanical waves; meaning, they require a medium to travel through.

Wrong Answered :
A
the medium`s particles are carried along with the wave
B
the wave`s energy passes from particle to particle
C
the medium transfers electromagnetic energy
D
the wave increases the potential two spherical energy
A wave is an propagation of energy along a medium. Waves need a medium in order for them to travel from one point or another. A wave is a particulate transfer of motion from one point to another. A very good example of the need of a medium is regarding sound. Sound cannot travel through a vacuum. This is because there are no air molecules to transfer the energy of the sound propagation. Hence no sound travels through the vacuum. The particle to particle interaction and vibration results in the transfer of energy in a wave propagation.

The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound

B
Amplitude
C
Frequency
D
Wavelength
The number of oscillations per second of a vibrating object is known as its frequency. Time period is the time required to complete one oscillation. Loudness of a sound is proportional to the square of the amplitude of its vibration.
