Explanation:
When discussing transverse waves, it is important to understand how the particles of a medium vibrate. Transverse waves are characterized by particles oscillating perpendicular to the direction of wave propagation. This means that the particles move in a direction that is at right angles to the direction in which the wave is moving.
Here is a detailed explanation of each option:
A: In the direction of wave propagation:
- This option is incorrect for transverse waves. In transverse waves, the particles do not vibrate in the same direction as the wave is moving.
B: Opposite to the direction of wave propagation:
- This option is also incorrect for transverse waves. The particles do not vibrate in the opposite direction of the wave propagation.
C: At right angles to the direction of wave propagation:
- This option is correct for transverse waves. The particles of the medium vibrate perpendicular to the direction of wave propagation.
D: None of the above:
- This option is incorrect. The correct answer is option C, as explained above.
In conclusion, the correct answer is C: "At right angles to the direction of wave propagation."

Particles of a medium in transverse waves vibrate at right angles to the direction of wave propagation. This means that their motion is perpendicular to the direction in which the wave is traveling. Let's explore this in more detail:
Explanation:
Transverse waves are characterized by the motion of particles in a medium that is perpendicular to the direction of wave propagation. This means that as the wave moves forward, the particles of the medium move up and down or side to side.
To understand this better, let's consider an example of a transverse wave on a string. If we create a wave on a string by shaking one end, the wave will travel along the string. However, if we observe the motion of individual particles in the string, we will notice that they move up and down as the wave passes through them. The particles do not move in the direction of the wave, but rather perpendicular to it.
Key Points:
1. Transverse waves are characterized by particles vibrating at right angles (perpendicular) to the direction of wave propagation.
2. The motion of particles in a transverse wave can be compared to the motion of a rope when you shake one end. The wave travels along the rope, but the particles of the rope move up and down.
3. Other examples of transverse waves include light waves, electromagnetic waves, and waves on the surface of water.
4. In contrast, longitudinal waves are characterized by particles vibrating in the same direction as the wave. An example of a longitudinal wave is a sound wave, where particles in the medium vibrate back and forth parallel to the direction of the wave.
In conclusion, in transverse waves, the particles of a medium vibrate at right angles to the direction of wave propagation. This characteristic motion is what distinguishes transverse waves from longitudinal waves.
