Question

As a transverse wave travels through a medium, it displaces the particles:

1. perpendicular to the motion of the wave.
2. vertically along the same plane as the wave.
3. parallel to the direction of the wave motion.
4.horizontally along the plane that the waves travels.

Question 2. As a longitudinal wave travels through a medium, it displaces the particles
1.parallel to the direction which the wave travels.
2.along the opposite plane of travel.
3.vertically along the direction that the wave travels.
4.perpendicular to the path of travel.

Answer 1

Transverse wave : perpendicular to the motion of the wave.

Longitudinal wave : parallel to the direction which the wave travels.

Step-by-step explanation:

(a) As a transverse wave travels through a medium, it displaces the particles perpendicular to the motion of the wave. It travels in the form of crest and trough. Electromagnetic wave is an example of transverse wave.

(b) As a longitudinal wave travels through a medium, it displaces the particles parallel to the direction which the wave travels. It travels in the form of compression and rarefaction. Sound wave is an example of longitudinal wave.

Answer 2

Transverse wave: 1. perpendicular to the motion of the wave

Longitudinal wave: 1.parallel to the direction which the wave travels.

Step-by-step explanation:

Waves are periodic oscillations that carry energy withouth transporting matter.

Depending on the direction of the oscillation, there are two types of waves:

- Transverse waves: in transverse waves, the direction of the oscillation is perpendicular to the direction of motion of the wave. Examples of transverse waves are electromagnetic waves (which consist of oscillating electric and magnetic fields that vibrate perpendicularly to the direction of motion of the wave)

- Longitudinal waves: in longitudinal waves, the direction of the oscillation is parallel to the direction of motion of the wave. Examples of longitudinal waves are sound waves (which consist of periodic vibrations of the particles of a medium, such as air. The vibrations create regions of higher density of particles, called compressions, and regions of lower density of particles, called rarefactions).
