Given,
Speed of EM wave,
For electromagnetic waves,
i.e.,
which is the required amplitude of electric field.
A radio can tune in to any station in the 7.5 MHz to 12 MHz band. What is the corresponding wavelength band?
Given,
Frequency band of radio = 7.5 MHz - 12 MHz
Therefore, the corresponding wavelength band is 40 m - 25 m.
