Welcome to Physical Science Grade 11/12 Alternative Delivery Mode (ADM) Module on the topic Models of the Universe (Greek Astronomy to Kepler)!
Our hands are the most represented parts of the human body. It is often used to depict skill, action, and purpose. With our hands, we create, accomplish and learn. Hence, you are capable and empowered to successfully achieve the relevant competencies and skills at your own pace and time. Your academic success lies in your own hands!
This module was designed to provide you with fun and meaningful opportunities for guided and independent learning at your own pace and time. You will be able to process the contents of the learning resource while being an active learner.
This module was designed and written with you in mind. It is to help you understand the nature of light. This module focuses on how light behaves as it encounters a boundary. It is called reflection of light which is fundamental in explaining the nature of light. In this module, the ray model of light will be used to help you comprehend the basics of image formation. You will be provided with different activities to help you master the concept. You can perform the activities according to your pace. You can use this module along with your Physical Science textbook or other learning resources.
This module has a single lesson:
- Lesson 1 – Reflection of Light
After going through this module, you are expected to:
1. Describe what happens when light is reflected;
2. Draw the path of light rays as they are reflected;
3. Identify and describe the following terms:
a. incident ray;
b. reflected ray;
c. the normal;
d. the angle of incidence; and
e. the angle of reflection.
4. Relate the angle of incidence and the angle of reflection;
5. Distinguish between diffuse and specular reflection;
6. Locate the image in a plane mirror; and
7. Explain how reflection can be used in an everyday object.
