Wave Frequency Formula:
| From: | To: |
Wave frequency (f) is the number of complete wave cycles that pass a given point per unit time. It is measured in Hertz (Hz), where 1 Hz equals one cycle per second. Frequency is a fundamental property of waves that determines their energy and, for electromagnetic waves, their color or pitch for sound waves.
The calculator uses the wave frequency formula:
Where:
Explanation: The formula shows that frequency is inversely proportional to wavelength - as wavelength increases, frequency decreases, and vice versa, when velocity remains constant.
Details: Calculating wave frequency is essential in various physics applications including optics, acoustics, radio communications, and quantum mechanics. It helps determine wave properties, energy levels, and how waves interact with different materials.
Tips: Enter wave velocity in meters per second (m/s) and wavelength in meters (m). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the relationship between frequency and energy?
A: For electromagnetic waves, higher frequency corresponds to higher energy (E = hf, where h is Planck's constant).
Q2: How does frequency affect sound waves?
A: Higher frequency sound waves are perceived as higher pitch, while lower frequency waves are heard as lower pitch.
Q3: What is the typical frequency range for visible light?
A: Visible light frequencies range from approximately 430 THz (red) to 750 THz (violet).
Q4: Can frequency be negative?
A: No, frequency is always a positive quantity as it represents the number of cycles per unit time.
Q5: How is frequency measured experimentally?
A: Frequency can be measured using various instruments including oscilloscopes, frequency counters, or by using the wave equation with known velocity and wavelength.
