Phase Difference Formula:
| From: | To: |
Phase difference (φ) is the difference in phase between two waves or oscillating quantities at the same frequency. It represents how much one wave leads or lags behind another and is measured in radians or degrees.
The calculator uses the phase difference formula:
Where:
Explanation: The formula calculates the phase difference by multiplying the angular frequency (2πf) by the time difference between the two waves.
Details: Phase difference is crucial in various fields including electrical engineering, acoustics, signal processing, and wave mechanics. It helps determine interference patterns, power factors in AC circuits, and synchronization of oscillating systems.
Tips: Enter frequency in Hertz (Hz) and time difference in seconds (s). Both values must be positive numbers. The calculator will compute the phase difference in radians.
Q1: What is the difference between phase difference and path difference?
A: Phase difference is measured in radians/degrees and represents temporal displacement, while path difference is measured in meters and represents spatial displacement between waves.
Q2: How do I convert radians to degrees?
A: Multiply the radian value by 180/π (approximately 57.2958) to convert to degrees.
Q3: What does a phase difference of π radians mean?
A: A phase difference of π radians (180°) means the waves are completely out of phase - when one wave is at maximum, the other is at minimum.
Q4: Can phase difference be negative?
A: Yes, negative phase difference indicates that one wave lags behind the other, while positive phase difference indicates it leads.
Q5: What are practical applications of phase difference?
A: Used in power factor correction, interference patterns in optics, sound engineering, radio communications, and vibration analysis.
