| From: | To: |
AM (Amplitude Modulation) radio wavelength refers to the physical length of one complete cycle of a radio wave in the AM broadcast band. The AM band operates at frequencies from 535 to 1605 kHz, corresponding to wavelengths of approximately 187 to 560 meters.
The calculator uses the wavelength formula:
Where:
Explanation: The formula calculates the distance a radio wave travels during one complete cycle based on its frequency and the constant speed of light.
Details: Understanding radio wavelength is crucial for antenna design, signal propagation analysis, and radio frequency planning. Different wavelengths behave differently in terms of propagation characteristics and antenna requirements.
Tips: Enter frequency in kHz within the AM band range (535-1605 kHz). The calculator will automatically convert to Hz and compute the corresponding wavelength in meters.
Q1: Why is wavelength important in radio communications?
A: Wavelength determines antenna size requirements and affects how radio waves propagate through different environments and over distances.
Q2: What is the relationship between frequency and wavelength?
A: Frequency and wavelength are inversely proportional - higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.
Q3: Why use the speed of light in the calculation?
A: Radio waves are electromagnetic waves that travel at the speed of light in a vacuum, which is approximately 3×10⁸ m/s.
Q4: How does AM wavelength compare to FM wavelength?
A: FM radio operates at much higher frequencies (88-108 MHz), resulting in much shorter wavelengths (approximately 2.8-3.4 meters).
Q5: Can this calculator be used for frequencies outside the AM band?
A: While the formula works for any frequency, this calculator is specifically designed for the standard AM broadcast band range.
