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

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

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

WordwallLearning Objective: To analyse how standing waves (SW) are formed

A – Predict how SW interfere

B – Predict how frequency changes affect SW

C – Evaluate conditions for SW

D – Explain conditions for formation of SW

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
