Inquiry-Based Learning Project "Exploring Optical Phenomena"

Task Description: Investigate the key concepts of optical phenomena, including total internal reflection, critical angle, and dispersion. Your task is to create a PowerPoint presentation to communicate your findings and understanding of these concepts. This assignment is divided into three parts, each addressing specific objectives.

Part 1: Total Internal Reflection (10 points) 1. Research and define the term "total internal reflection". 2. Provide an example of a real-world application utilizing total internal reflection. 3. Explain the conditions that must be met for total internal reflection to occur. 4. Create for the above points, including visual aids, diagrams, or images to enhance understanding.

Part 2: Atmospheric Refraction (10 points) 1. Define the term "critical angle". 2. Explain how the critical angle relates to the concept of total internal reflection. 3. Research and describe atmospheric conditions that can cause refraction of light in the Earth's atmosphere. 4. Discuss a specific example of a natural phenomenon caused by atmospheric refraction and provide an explanation. 5. Create for the above points, including visual aids, diagrams, or images to enhance understanding.

Part 3: Dispersion and Rainbows (10 points) 1. Define "dispersion" in the context of light. 2. Explain how the index of refraction is related to the phenomenon of dispersion. 3. Research and describe how rainbows are formed, specifically in terms of the dispersion of light. 4. Explain why different colours are seen in a rainbow and their order. 5. Create for the above points, including visual aids, diagrams, or images to enhance understanding.
