The medium matters

The same frequency can have a tiny electromagnetic wavelength or a human-scale sound wavelength because the wave speed is different. That is why "frequency" by itself is not enough context for a physics claim, a Tesla claim, or a device claim.

Converter FAQ

How do you convert frequency to wavelength?

Divide the wave speed by the frequency: wavelength = speed / frequency. The speed must match the medium.

Why is sound different from electromagnetic waves?

Sound is a mechanical wave whose speed depends on the medium. Electromagnetic waves in vacuum travel at about 299,792,458 meters per second.

Does a frequency value alone prove a Tesla claim?

No. Frequency is a real measurement, but historical and scientific claims still need sources and context.
