Radio waves have wavelengths that range from several millimeters to several kilometers. The specific wavelength of a radio wave depends on its frequency, as they are inversely proportional to each other according to the wave equation v = λf, where v is the wave speed, λ is the wavelength, and f is the frequency.
Here are some approximate ranges of radio wave wavelengths corresponding to different frequency bands:
- Extremely Low Frequency (ELF): Wavelengths can be thousands of kilometers long.
- Very Low Frequency (VLF): Wavelengths range from several kilometers to tens of kilometers.
- Low Frequency (LF): Wavelengths are typically in the range of hundreds to thousands of meters.
- Medium Frequency (MF): Wavelengths are generally in the range of tens to hundreds of meters.
- High Frequency (HF): Wavelengths range from several to tens of meters.
- Very High Frequency (VHF): Wavelengths typically range from a few centimeters to several meters.
- Ultra High Frequency (UHF): Wavelengths are typically in the range of several centimeters to tens of centimeters.
- Microwave Frequency (Microwave): Wavelengths can range from millimeters to centimeters.
It's worth noting that these are approximate ranges and can vary depending on the source you consult and the specific frequency bands defined by different organizations or applications.
