|
Reflection from a smooth surface in a single direction is called specular reflection. |
|
(Physics only) What is spectacular reflection? Observe the different reflection angles for smooth and rough surfaces |
|
|
|
Reflection from a rough surface causes scattering: this is called diffuse reflection. |
|
(Physics only) What is diffused reflection? Create a matrix map to compare the different properties of spectacular and diffused reflection. |
|
|
|
Waves can be reflected at the boundary between two different materials. |
|
Where are rays reflected from? Use ray boxes to remind students of the properties that all EM waves have but that we can observe using visible light. |
|
|
|
The time taken for the reflections to reach a detector can be used to determine how far away such a boundary is. This allows ultrasound waves to be used for both medical and industrial imaging. |
|
What can the time taken for the reflections to reach a detector be used to determine? Consider the applications of waves in medicine to suggest how their reflective properties can be taken advantage of |
|
|
|
Students should be able to construct ray diagrams to illustrate the reflection of a wave at a surface. |
|
(Physics Only)How could a ray diagram to illustrate the reflection of a wave at a surface? Draw accurate ray diagrams for the observations made. |
|
|
|
Ultrasound waves are partially reflected when they meet a boundary between two different media. |
|
What happens to
Ultrasound waves when they meet a boundary? EW: Compare and contrast the properties of visible light and UV waves |
