It increases and is perpendicular to the motion of the wave.
It decreases and is perpendicular to the motion of the wave.
It increases and is parallel to the motion of the wave.
It decreases and is parallel to the motion of the wave.

Answer 1

It increases and is perpendicular to the motion of the wave.

Answer 2

It increases and is perpendicular to the motion of the wave.

Step-by-step explanation:

- A transverse wave is a wave in which the oscillation occurs in a direction perpendicular to the motion of the wave (example of transverse waves are electromagnetic waves)

- A longitudinal wave is a wave in which the oscillation occurs in a direction parallel to the motion of the wave (example of longitudinal waves are sound waves)

- The amplitude of a wave is defined as the maximum displacement of the wave relative to the equilibrium position, and the energy carried by the wave is proportional to the square of the amplitude:

`E\propto A^2`

Therefore, as the amplitude of the wave increases, the energy increases as well.
