Activity 1: Understanding Reflection and Refraction

Read each question carefully and use your knowledge of light to answer. Consider the behaviour of light when it encounters different surfaces and materials.

1. Describe how light behaves when it hits a smooth, shiny surface. ______
2. Explain the difference between reflection and refraction. ______
3. What is the angle of incidence if the angle of reflection is 35°? ______

Activity 2: Calculating the Speed of Light in Different Media

Use the refractive index to calculate the speed of light in various media. Remember that the speed of light in a vacuum is approximately 3.00 x 10^8 m/s.

1. Calculate the speed of light in water (n = 1.33). ______
2. Calculate the speed of light in glass (n = 1.50). ______
3. Calculate the speed of light in diamond (n = 2.42). ______
