The Total solution for NCERT class 6-12
A radio can tune in to anystation in the 7.5 MHz to 12 MHz band. What is the corresponding wavelengthband?
A radio can tune to minimumfrequency, ν1 = 7.5 MHz= 7.5 × 106 Hz
Maximumfrequency, ν2 = 12 MHz = 12 × 106 Hz
Speed oflight, c = 3 × 108 m/s
Corresponding wavelength for ν2 can be calculated as:
Thus, the wavelength band of theradio is 40 m to 25 m.
