Waves - Characteristics of waves: reflection

By the end of the lesson, the learner should be able to:

- Explain how to determine the focal length of a concave mirror
- Perform an experiment to determine the focal length of a concave mirror
- Value the practical approach in determining properties of mirrors

- Demonstrate reflection of waves in a ripple tank
- Verify that waves obey the laws of reflection
- Appreciate that various wave types follow similar behavior patterns

- Set up a concave mirror to focus an image of a distant object on a screen
- Measure the distance between the mirror and the screen
- Record and analyze the results to determine the focal length
- Set up a ripple tank with barriers to demonstrate wave reflection
- Observe reflection patterns with barriers at different angles
- Compare the incident and reflected waves
- Verify the laws of reflection for water waves

Why is it important to know the focal length of a concave mirror?
How are waves reflected at barriers?
