Part A: Fill in the blanks

#### 1) All mirrors ______ light.
✔ Answer: *Reflect*
Explanation: Mirrors reflect light rays; this is their primary function.

---

#### 2) There are three types of mirrors. All three types reflect light rays to form ______.
✔ Answer: *Images*
Explanation: Mirrors form images—either real or virtual—depending on the type of mirror and object position.

---

#### 3) A ______ is a mirror that is flat and smooth. It produces an image that is the same size as the object and appears to be the same distance from the mirror as the object.
✔ Answer: *Plane mirror*
Explanation: A plane mirror is flat and reflects light to form a virtual, upright, same-sized image behind the mirror at equal distance.

---

#### 4) A ______ is a mirror that curves inward. The image formed by this type of mirror depends on how far away the object is from the ______.
✔ Answer: *Concave mirror*, *focal point*
Explanation: A concave mirror curves inward (like a cave). The image characteristics depend on the object’s distance relative to the focal point.

> Note: "Focal point" is the correct term here because the behavior of the image changes based on whether the object is beyond, at, or between the center of curvature and focal point.

---

#### 5) Light rays that come together at a focal point are described as ______.
✔ Answer: *Converging*
Explanation: When light rays bend toward a single point (the focal point), they are converging.

---

#### 6) If the object is far from the concave mirror, its image is small and ______.
✔ Answer: *Upside down*
Explanation: For objects placed beyond the center of curvature of a concave mirror, the image is real, inverted (upside down), and smaller than the object.

---

#### 7) If the object is close to a concave mirror, then the image appears to be larger than the object and is ______.
✔ Answer: *Upright*
Explanation: When the object is within the focal length of a concave mirror, the image is virtual, upright, and magnified (larger).

---

#### 8) A ______ is a mirror that curves outward. It reflects parallel light rays as if they came from a focal point ______ the mirror.
✔ Answer: *Convex mirror*, *behind*
Explanation: A convex mirror curves outward. Parallel rays reflect and appear to diverge from a focal point located behind the mirror (virtual focal point).

---

#### 9) Light rays that spread apart after reflecting are described as ______.
✔ Answer: *Diverging*
Explanation: Diverging rays move away from each other after reflection, like those from a convex mirror.

Part B: Match each Term with the best Descriptor

| Term | Descriptor |
|-------------------|--------------------------------|
| Diverging | C. Spreading apart |
| Converging | A. Coming together |
| Plane mirror | D. Is smooth and flat |
| Convex mirror | E. Curves outwards |
| Concave mirror | B. Curves inwards |

✔ Explanation:
- Diverging: Rays spread apart → matches C
- Converging: Rays come together → matches A
- Plane mirror: Flat surface → matches D
- Convex mirror: Curves outward → matches E
- Concave mirror: Curves inward → matches B

---

✔ Final Answers:

#### Fill-in-the-blanks:
1) Reflect
2) Images
3) Plane mirror
4) Concave mirror, focal point
5) Converging
6) Upside down
7) Upright
8) Convex mirror, behind
9) Diverging

#### Matching:
- Diverging → C. Spreading apart
- Converging → A. Coming together
- Plane mirror → D. Is smooth and flat
- Convex mirror → E. Curves outwards
- Concave mirror → B. Curves inwards
