Answer

To solve the problem of matching the items in List-I with those in List-II, we will analyze each term in List-I and find its corresponding match in List-II based on the principles of wave optics.

### Step-by-Step Solution:

1. **Interference (a)**:
- Interference refers to the phenomenon where two or more waves superpose to form a resultant wave. In this case, the result is characterized by bands of equal width, known as fringe width.
- **Match**: G (bands of equal width).

2. **Diffraction (b)**:
- Diffraction is the bending of waves around obstacles and the spreading of waves when they pass through small openings. The resulting pattern typically shows bands of unequal width due to the varying intensity of light.
- **Match**: H (bands of unequal width).

3. **Polarization (c)**:
- Polarization is the process by which the vibrations of light waves are restricted to a particular direction. This phenomenon is indicative of the transverse nature of light waves.
- **Match**: E (transverse nature of light).

4. **Dichroism (d)**:
- Dichroism refers to the phenomenon where a material exhibits different colors when viewed from different angles or when different polarizations of light pass through it. This effect arises from the unequal absorption of ordinary and extraordinary rays.
- **Match**: F (unequal absorption of ordinary and extraordinary ray).

### Final Matches:
- a) Interference → G (bands of equal width)
- b) Diffraction → H (bands of unequal width)
- c) Polarization → E (transverse nature of light)
- d) Dichroism → F (unequal absorption of ordinary and extraordinary ray)

### Summary of Matches:
- A → G
- B → H
- C → E
- D → F
