Hello,

I need help answering Q2 and Q3.

Thank you!

**Figure 3: Ray Tracing Diagram Description**

This diagram illustrates the process of ray tracing for a converging lens, where the object distance (\( d_o \)) is greater than the focal length (\( f \)). The setup shows an object on the left side of the lens.

**Instructions:**

- Insert the three principal rays for a converging lens on the diagram. The line segment can be manipulated to form these rays.
- Use different colors for each ray and label them accordingly.

**Key Points:**

- The lens is thin, so all refraction occurs at the vertical center line.
- Principal rays help determine the image location and characteristics.
- Only three principal rays are needed for image location.

**Q2: Image Analysis**

1. Insert a line with an arrowhead on the diagram to represent the image. 
2. Determine the nature of the image:
   - Real or virtual? (Highlight one)
   - Upright or inverted? (Highlight one)
   - Magnified or reduced? (Highlight one)

**Measurements:**

- Focal Length (\( f \)): 7.5 cm
- Object Distance (\( d_o \)): 11.5 cm
- Object Height (\( h_o \)): 3 cm
- Image Distance (\( d_i \)) Measurement: 7.5 cm
- Image Height (\( h_i \)) Measurement: 2 cm

**Equations:**

- Equation 1: \(\frac{1}{d_o} + \frac{1}{d_i} = \frac{1}{f}\)
- Equation 2: \(M = \frac{h_i}{h_o} = -\frac{d_i}{d_o}\)

**Task:**

- Calculate \( d_i \) and Magnification (M). Use the given equations, and insert your solution.
- Check if calculated and measured values align, and resolve any discrepancies.

**Q3: Analysis**

- Compare calculated and measured values of \( d_i \) and M.
- Discuss any discrepancies and make necessary adjustments.
