The transverse nature of light is shown by

Options

A. interference of light
B. refraction of light
C. polarisation of light
D. dispersion of light

Answer

To determine how the transverse nature of light is shown, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Transverse Waves**:
- A transverse wave is characterized by oscillations that occur perpendicular to the direction of wave propagation. For light waves, the electric and magnetic fields oscillate at right angles to the direction in which the wave travels.

2. **Identifying Light as a Transverse Wave**:
- Light is an electromagnetic wave, which means it consists of oscillating electric and magnetic fields. These oscillations are perpendicular to the direction of the wave's travel, confirming its transverse nature.

3. **Exploring the Phenomenon of Polarization**:
- Polarization is a process that restricts the vibrations of light waves to a particular direction. When unpolarized light (which vibrates in multiple directions) passes through a polarizer, it becomes polarized, meaning its vibrations are aligned in a specific direction.

4. **Demonstrating Polarization**:
- When unpolarized light hits a polarizer, only the component of the light wave that aligns with the polarizer's axis passes through. This process effectively demonstrates the transverse nature of light, as the electric field vector of the polarized light oscillates in a single plane.

5. **Conclusion**:
- The transverse nature of light is confirmed by the phenomenon of polarization. Thus, the correct answer to the question is that the transverse nature of light is shown by the polarization of light.

### Final Answer:
The transverse nature of light is shown by the phenomenon of polarization.
