Learning Objective
At the end of the lesson, you will understand the concept of refraction and its effects on light as it passes through different mediums.
What is Refraction?
Refraction is the bending of light as it passes from one medium to another, due to a change in speed.
The Law of Refraction
The angle of incidence and the angle of refraction are related by Snell's Law: n1 * sin(θ1) = n2 * sin(θ2).
Cooperative Learning Activity
In groups, discuss real-world examples of refraction, such as lenses, rainbows, and prisms.
Differentiated Instruction: Group Task
Groups will create a poster explaining refraction in one chosen example. Use visuals and key points.
Interactive Experiment: Refraction in Water
Observe how a pencil appears bent in water. Discuss why this occurs based on refraction concepts.
Class Discussion: Refraction's Impact
Discuss how refraction affects vision and technology, like eyeglasses and cameras.
