Lesson Title: Today we are learning about
How is diffused reflection different spectacular reflection?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Reflection from a smooth surface in a single direction is called specular reflection.
  2. Reflection from a rough surface causes scattering: this is called diffuse reflection.
  3. Waves can be reflected at the boundary between two different materials.
  4. 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.
  5. Students should be able to construct ray diagrams to illustrate the reflection of a wave at a surface.
  6. Ultrasound waves are partially reflected when they meet a boundary between two different media.
Think about how you can match the needs of ALL students
Keywords:
  • Boundary: point where two materials of different density meet (1)
  • Detector: a device or instrument designed to detect the presence of a particular object or substance. (1)
  • Waves: Transfer energy, not matter. (1)
  • Ultrasound: Electromagnetic wave (1)

AFL/Key Questions:
  1. (Physics only) What is spectacular reflection?
    Reflection from a smooth surface in a single direction is called specular reflection.
  2. (Physics only) What is diffused reflection?
    Reflection from a rough surface causes scattering: this is called diffuse reflection.
  3. Where are rays reflected from?
    Waves can be reflected at the boundary between two different materials.
  4. What can the time taken for the reflections to reach a detector be used to determine?
    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.
  5. (Physics Only)How could a ray diagram to illustrate the reflection of a wave at a surface?
    A ray diagram could be used to show a reflection using straight lines with arrows on to show the direction of the light wave. The light wave would bounce back at the same angle.
  6. What happens to Ultrasound waves when they meet a boundary?
    Ultrasound waves are partially reflected when they meet a boundary between two different media.

Starter Activity Differentiation and Challenge question/task
  • Students to copy and complete the keywords.
  • Teacher reveals missing letters; Students correct mistakes;
  • Discuss the scientific meanings of the words.
  • Students to write down the definitions of the most important / new keywords.
  • Discuss the 'Memory Anchor'.
    • What does it show?
    • How does it relate to the what we are learning about today (title)?
Think about PACE – Develop, consolidate and deepen knowledge, skills and understanding
