Phasor Diagrams
Below is a phasor diagram.
The blue and red vectors are complex numbers.
Each one is associated with a wave.
Answer the questions below.
Vary the length of the red and blue vectors with the sliders. What is the relationship between the red vector and the amplitude of the wave?
Move the two complex vectors. The arguments of the vectors are shown by the vectors. What is the relationship between the vector angle and the phase shift of the waves?
Now turn on the add waves button. The two vectors are added together. What is the relationship between the vectors magnitude and the wave sum?
