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

Text Solution

Verified by Experts

We know that wave length, `lamda = c/v`
hence, `lamda = (3xx10^8)/(7.5 xx10^6) = 6/15xx10^2 m^3 = 0.4 xx10^2 m`
and `lamda'=(3xx10^8)/(12xx10^6) = 0.25xx10^2 m`
The band of wavelengths will be 25m to 40m.
