Quarter 2 MELC 9 Concave and Convex Mirror Worksheet by HYDEE BALBA - Free Printable

It looks like you've uploaded a worksheet titled "Concave and Convex Mirror Worksheet" from a physics or optics lesson. The task involves drawing ray diagrams for different object positions in front of concave and convex mirrors, using the rules of ray tracing to determine image location, size, orientation, and type (real/virtual).

Since I can't view images directly, I'll help you solve this based on the typical structure of such worksheets. Below is a step-by-step explanation of how to approach each diagram, assuming the standard setup:

🔍 General Rules for Ray Tracing in Mirrors

#### For Concave Mirrors:
- Rays parallel to the principal axis reflect through the focal point (F).
- Rays passing through the focal point reflect parallel to the principal axis.
- Rays passing through the center of curvature (C) reflect back along the same path.

#### For Convex Mirrors:
- Rays parallel to the principal axis reflect as if they came from the focal point behind the mirror.
- Rays directed toward the center of curvature reflect at equal angles.
- Rays appear to diverge from the focal point after reflection.

📌 Common Object Positions & Image Characteristics

| Object Position | Concave Mirror Image | Convex Mirror Image |
|------------------|------------------------|------------------------|
| Beyond C | Real, inverted, smaller | Virtual, upright, smaller |
| At C | Real, inverted, same size | Virtual, upright, smaller |
| Between C and F | Real, inverted, larger | Virtual, upright, smaller |
| At F | Image at infinity | Virtual, upright, smaller |
| Between F and mirror | Virtual, upright, larger | Virtual, upright, smaller |

Now let’s assume your worksheet has four diagrams with labeled points:
- C: Center of curvature
- F: Focal point
- O: Object position (marked by an arrow)
- A horizontal line representing the principal axis

Let me walk through how to solve each one.

✔ Diagram 1: Concave Mirror – Object beyond C

```
O
/ \
/ \
/ \
/_______\
C F
```

#### Steps:
1. Draw a ray from the top of the object parallel to the axis → reflects through F.
2. Draw a ray from the top through F → reflects parallel.
3. Draw a ray from the top through C → reflects back on itself.

✔ These rays converge between C and F → image is real, inverted, smaller.

👉 Use different colored lines for each ray (e.g., red = parallel, blue = through F, green = through C).

✔ Diagram 2: Convex Mirror – Object in front

```
O
/ \
/ \
/ \
/_______\
C F (behind)
```

#### Steps:
1. Draw a ray parallel to the axis → appears to come from F behind.
2. Draw a ray toward C → reflects symmetrically.
3. Extend reflected rays backward — they appear to meet behind the mirror.

✔ Image is virtual, upright, smaller, located behind the mirror.

✔ Diagram 3: Concave Mirror – Object between F and mirror

```
O
/ \
/ \
/ \
/_______\
F C
```

#### Steps:
1. Ray parallel → goes through F.
2. Ray through F → becomes parallel.
3. Ray toward C → reflects back.

✘ Rays diverge after reflection → extend backward to find intersection.

✔ Image is virtual, upright, larger than object, behind the mirror.

---

✔ Diagram 4: Convex Mirror – Object anywhere

```
O
/ \
/ \
/ \
/_______\
F (behind) C (behind)
```

#### Steps:
1. Ray parallel → appears to come from F.
2. Ray toward C → reflects symmetrically.
3. Backward extensions meet behind mirror.

✔ Always forms virtual, upright, diminished image.

✔ How to Fill Out the Worksheet

For each diagram:

1. Draw three rays (use different colors).
2. Label:
- Object (O)
- Image (I)
- F and C
- Principal axis
3. Write "Concave or Convex" in the box.
4. In the "Label" column, write:
- Real/Virtual
- Upright/Inverted
- Larger/Smaller/Same Size

🧩 Example Answer Format

| Diagram | Concave or Convex | Label |
|--------|--------------------|-------|
| 1 | Concave | Real, Inverted, Smaller |
| 2 | Convex | Virtual, Upright, Smaller |
| 3 | Concave | Virtual, Upright, Larger |
| 4 | Convex | Virtual, Upright, Smaller |

If you can describe the exact setup of each diagram (e.g., "object is between F and mirror in concave mirror"), I can give specific instructions for drawing the rays.
