Calculation of RF wave length - aneeshkms - 09-29-2016 09:49 AM
hi sir
in the dielectric artifact topic its mentioned that at 1.5 T the wave length is 52 cm , at 3 T 26 cm and 7 T it is 11 cm.
Just I want to know how the length of the wave is calculated.
And how the wave length bigger in lower Tesla machines?
kindly let me know please.
with thanks in advance

Wavelength is velocity divided by frequency. For electromagnetic radiation, velocity is the speed of light. Because the frequency is smaller in lower Tesla machines, the wavelength is longer.
