Answer

To solve the problem, we need to match the optical components in Column I with the appropriate optical phenomena in Column II. Let's analyze each optical component step by step.

### Step 1: Analyze Convex Mirror (A)
- A convex mirror always forms a **virtual image**. This is because the reflected rays diverge, and the image appears to be behind the mirror.
- Convex mirrors do not cause **dispersion**; they primarily reflect light without separating it into different colors.
- Therefore, the correct matches for the convex mirror are:
- (s) Virtual images of real objects
- (q) Deviation is not applicable here.

**Matches: (s)**

### Step 2: Analyze Converging Lens (B)
- A converging lens (or convex lens) can form both **real** and **virtual images** depending on the position of the object relative to the focal point.
- It can cause **dispersion** (separation of light into its component colors) and **deviation** (bending of light rays).
- Therefore, the correct matches for the converging lens are:
- (p) Dispersion
- (q) Deviation
- (r) Real image of real object
- (s) Virtual images of real objects (when the object is between the focal point and optical center).

**Matches: (p), (q), (r), (s)**

### Step 3: Analyze Thin Prism (C)
- A thin prism causes **dispersion** as it separates light into its constituent colors when light passes through it.
- It also causes **deviation** of light rays.
- Prisms do not form real images; they can only form virtual images.
- Therefore, the correct matches for the thin prism are:
- (p) Dispersion
- (q) Deviation
- (s) Virtual images of real objects.

**Matches: (p), (q), (s)**

### Step 4: Analyze Glass Slab (D)
- A glass slab does not cause **dispersion**; it only refracts light without separating it into colors.
- It does not cause **deviation** in the sense of changing the path of light significantly; the light emerges parallel to its original direction.
- However, it can create a **virtual image** due to the bending of light at the boundaries.
- Therefore, the correct match for the glass slab is:
- (s) Virtual images of real objects.

**Matches: (s)**

### Final Matches Summary:
- (A) Convex mirror → (s)
- (B) Converging lens → (p), (q), (r), (s)
- (C) Thin prism → (p), (q), (s)
- (D) Glass slab → (s)
