More Relative Phases

• Oscillations and Waves 2023 The following voltage traces are observed on an oscilloscope:
  

  

  1. What is the cyclic frequency and the angular frequency of the blue trace

  2. What is the cyclic frequency and the angular frequency of the yellow trace?

  3. Considering the blue signal as the “reference", is the yellow trace ahead or behind? Why?

  4. What is the phase of the yellow trace relative to the blue trace (i) in seconds, (ii) in cycles, (iii) in radians? Include the sign.
