A radio can tune into any station in the 7.5 MHz to 12 MHz band. What is the corresponding wavelength band ?
Text Solution
Verified by Experts
Frequency of 7.5 MHz belongs to SW band. The corresponding wavelength is `lambda=(c)/(v)=(3xx10^(8))/(7.5xx10^(6))=40km` Frequency of 12 MHz belongs to HF band, the corresponding wavelength is`lambda=(c)/(v)=(3xx10^(8))/(12xx10^(6))=25km` Corresponding to the given frequency band, the wavelength band is 25 m - 40 m band.
