Frequency Formula:
| From: | To: |
The frequency formula calculates the frequency of a wave from its wavelength and the speed of light. It is a fundamental equation in physics and electromagnetic theory.
The calculator uses the frequency formula:
Where:
Explanation: The formula shows the inverse relationship between frequency and wavelength - as wavelength increases, frequency decreases, and vice versa.
Details: Frequency calculation is essential in various fields including telecommunications, radio broadcasting, optics, and quantum mechanics. It helps determine the energy of electromagnetic waves and their behavior in different media.
Tips: Enter wavelength in meters. The value must be valid (wavelength > 0). The calculator will automatically use the speed of light constant (3×10⁸ m/s) for the calculation.
Q1: What is the relationship between frequency and wavelength?
A: Frequency and wavelength have an inverse relationship. As frequency increases, wavelength decreases, and vice versa, when the speed of wave propagation is constant.
Q2: Why is the speed of light used in this formula?
A: For electromagnetic waves (including light, radio waves, etc.), the speed of propagation in vacuum is constant at approximately 3×10⁸ m/s.
Q3: Can this formula be used for other types of waves?
A: Yes, the general formula f = v/λ applies to all waves, where v is the wave velocity. For electromagnetic waves in vacuum, v = c.
Q4: What are typical frequency ranges for different applications?
A: Radio waves: 3 kHz-300 GHz, Microwaves: 300 MHz-300 GHz, Infrared: 300 GHz-430 THz, Visible light: 430-750 THz, UV: 750 THz-30 PHz.
Q5: How does frequency relate to energy?
A: For electromagnetic waves, energy is directly proportional to frequency (E = hf, where h is Planck's constant). Higher frequency waves carry more energy.
