Which of the following is an example of transverse wave motion ?

Options

A. Light waves coming from Sun to Earth.
B. When a spring is pulled sidewaves, the kink moves `90^(@)` to the length of spring.
C. Movement of the membrane of tabla.
D. Vibrations of air column above the surfave of water in a resonance tube.

Answer

To determine which of the given options is an example of transverse wave motion, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Transverse Waves**:
- Transverse waves are characterized by oscillations that occur perpendicular to the direction of wave propagation. This means that if the wave is moving horizontally, the oscillations occur vertically.

2. **Option 1: Light Waves from the Sun to Earth**:
- Light waves are electromagnetic waves that propagate through space. The electric and magnetic fields oscillate perpendicular to the direction of wave travel, making light waves a classic example of transverse waves.
- **Conclusion**: This option is correct.

3. **Option 2: Kink in a Spring**:
- When a spring is pulled sideways and then released, the kink (or disturbance) moves perpendicular to the length of the spring. This also demonstrates transverse wave motion, as the movement of the kink is at a right angle to the direction of the wave's travel.
- **Conclusion**: This option is also correct.

4. **Option 3: Movement of the Membrane of a Tabla**:
- When you strike the membrane of a tabla, it vibrates up and down. The oscillation of the membrane is again perpendicular to the direction of the wave propagation, which can be considered transverse wave motion. However, since the ends of the membrane are fixed, it creates standing waves rather than traveling waves.
- **Conclusion**: This option is correct as well.

5. **Option 4: Vibration of Air Column in a Resonance Tube**:
- The vibration of an air column is associated with sound waves, which are longitudinal waves. In longitudinal waves, the oscillations occur in the same direction as the wave propagation, meaning this does not qualify as transverse wave motion.
- **Conclusion**: This option is incorrect.

### Final Answer:
The examples of transverse wave motion are:
- Light waves from the Sun to Earth (Option 1)
- Kink in a spring (Option 2)
- Movement of the membrane of a tabla (Option 3)

The incorrect option is the vibration of the air column in a resonance tube (Option 4).
