Question

While I can't draw diagrams directly, I can guide you through creating a model of light refraction through a glass lens.
### Steps to Create a Diagram of Light Refraction through a Glass Lens
1. **Draw the Lens:**
- Sketch a convex lens (which is thicker in the middle than at the edges). This could be represented by an elongated oval shape.
2. **Draw the Optical Axis:**
- Draw a straight horizontal line through the center of the lens. This is called the optical axis.
3. **Incident Light Rays:**
- Draw several arrows (representing light rays) coming in from the left, approaching the lens. Mark one of the incident rays as "Ray 1" and another as "Ray 2".
4. **Label Angles:**
- For Ray 1, indicate the angle of incidence (i) as the angle between the incident ray and the normal line (a dashed vertical line) drawn at the point where the ray hits the lens. For Ray 1, label the angle of refraction (r) as the angle between the refracted ray and the normal in the glass.
5. **Draw Refracted Light Rays:**
- As the rays pass through the lens, show them bending towards the normal as they enter the glass (for Ray 1) and bending away from the normal as they leave. Ray 1 would bend towards the optical axis after refraction.
6. **Repeat for Ray 2:**
- Draw Ray 2 approaching the lens at a different angle, following the same labeling for angles of incidence (i2) and refraction (r2).
7. **Highlight the Focal Point:**
- Mark and label the focal point (F) on the right side of the lens, where the refracted rays converge.
### Key Observations:
- **Angle of Incidence vs. Angle of Refraction:**
- When light travels from air into glass (a denser medium), it bends towards the normal line, meaning the angle of refraction (r) is less than the angle of incidence (i).
- When leaving the glass back into air, the light bends away from the normal line, so the angle of refraction (r) is greater than the angle of incidence (i) in this case.
### Final Notes:
- The shapes and angles of the light rays may vary depending on the curvature of the lens and the angle at which the light approaches the lens.
- The laws of refraction that apply here are described by Snell's Law, which mathematically expresses the relationship between the angles of incidence and refraction based on the indices of refraction of the two media.
This model will help you visualize and understand the behavior of light as it passes through a glass lens, showing the change in direction that results from refraction.
