Question : 5
Total: 15
A radio can tune in to any station in the 7.5 MHz to 12 MHz ban. What is the corresponding wavelength band?
Solution:
Maximum wavelength in the band is for lowest frequency
c =v min λ max
λ max
Minimum wavelength in the band is for highest frequency
c =v max λ min
λ min
So, the wavelength band for tuning is between 25 m to 40 m.
c =
Minimum wavelength in the band is for highest frequency
c =
So, the wavelength band for tuning is between 25 m to 40 m.
