A radio can tune to any station in 7.5 MHz to 12MHz band. The corresponding wavelength band isA. 40 M to 25 mB. 30 m to 25 mC. 25 m to 10 mD. 10 m to 5 m |

Answer» Correct Answer - A Here, `upsilon_(1)=7.5"MHz," upsilon_(2)="12 MHz"` `therefore" "lambda_(1)=(c)/(upsilon_(1))=(3xx10^(8))/(7.5xx10^(6))=40m` and `lambda_(2)=(c)/(upsilon_(2))=(3xx10^(8))/(12xx10^(6))=25m` |
