A radio can tune to any station in 7.5 MHz to 12MHz band. The corresponding wavelength band is

Options

A. 40 M to 25 m
B. 30 m to 25 m
C. 25 m to 10 m
D. 10 m to 5 m

Answer

A

Explanation

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`
