A radio can tune to any station in 6 MHz to 10 MHz band. The value of corresponding wavelength bandwidth will be

Step-by-step solution

Given: Frequency f 1 = 6 MHz Frequency f 2 = 10 MHz Wavelength can be calculated using λ = c f . ⇒ λ 1 = c f 1 = 3 × 10 8 6 × 10 6 = 50   m ⇒ λ 2 = c f 2 = 3 × 10 8 10 × 10 6 = 30   m Wavelength bandwidth is the difference of upper lower wavelengths = λ 1 - λ 2 = 20   m
