What term describes the angle between two sinusoidally varying quantities with the same frequency?

• A. Phase Angle
• B. Phase Shift
• C. Wavelength
• D. Frequency

Answer: (A)

When two sinusoids share the same frequency, their relationship is described by a phase difference—the angular offset between their cycles. This phase angle tells you how far one waveform leads or lags the other within each cycle. Wavelength is about spatial distance between repeating points, and frequency is about how often cycles occur per second, so they don’t describe the relative angular alignment. Phase shift is related, but the term that directly expresses the angular separation between the two waves is phase angle.
