Presentation Transcript

  1. B – Predict variations in PD and EMF in circuits Wordwall Learning Objective: To analyse EMF and voltage in circuits A – Predict how resistivity affects EMF D – Identify circuit symbols C – Compare EMF and potential difference

  2. Our initial problem? How can this mask mean you never charge your ipod? How would you calculate the EMFof this? Why are we learning this? EMF sums up how powerful ALL electric things are

  3. (C) List conditions necessary for a standing wave to occur D – Explain conditions for formation of SW C – Evaluate conditions for SW

  4. Group roles WRITER OF EXPLANATIONS DRAWER/CALCULATOR OF PHASE DIFFERENCE Extra role: KEY WORDS AND MEANINGS

  5. Task 1: What are nodes and antinodes? Why do we need nodes and antinodes in a stationary wave? Why would the waves need to travel in opposite directions? Why does the energy not become lost? “A stationary wave is not alongitudinal or a transverse Wave” – Why? C – Evaluate conditions for SW

  6. Task 2: Define frequency, node andantinode Why do we get visible nodes and antinodes when the waves that make up the stationary wave are in phase? What would happen if the waves are out of phase “nodes and antinodes cannot happen if the waves have different frequencies” Why? B – Predict how frequency changes affect SW

  7. Wordwall Learning Objective: To analyse how standing waves (SW) are formed A – Predict how SW interfere B – Predict how frequency changes affect SW D – Explain conditions for formation of SW C – Evaluate conditions for SW

  8. Back to Saturn’s north pole (D) Predict how Saturn’s cloud would form (C) Create an explanation for what conditions astronaughts need to check for (B) Water and wind cause clouds. Why do we require winds of the same frequency for the clouds to be stationary waves? (A) If 2 stationary waves interfered and were moving towards each other, predict what would happen

  9. Wordwall Learning Objective: To analyse how standing waves (SW) are formed A – Predict how SW interfere B – Predict how frequency changes affect SW D – Explain conditions for formation of SW C – Evaluate conditions for SW
