A radio can tune in to any station in the 7.5 MHz to 12 MHz band. What is the corresponding wavelength band? |

Answer» Solution :WAVELENGTH corresponding to frequency of 7.5 MHz `(or 7.5xx10^(6)Hz)` is `lambda_(1)=(C )/(v)=(3xx10^(8))/(7.5xx10^(6))=40m` and wavelength corresponding to frequency of 12 MHz `(or 12xx10^(6)Hz)` `lambda_(2)=(3xx10^(8))/(12xx10^(6))=25m` Thus, wavelength band is `25m-40m`. |
