1.	A radio can tune in to any station in the 7.5 MHz to 12 MHz band. What is the corresponding wavelength band?
Answer» Given: V₁ = 7.5 MHz = 7.5 × 10⁶Hz, V₁ = 12 MHz = 12 × 10⁶ Hz. To find: Wavelength band Formula: λ = \(\frac{c}{v}\) Calculation: From formula, V₁ = \(\frac{3\times10^8}{7.5\times10^6}\) = 40 m V₁ = \(\frac{3\times10^8}{12\times10^6}\) = 25 m ∴ Wavelength band = 40 m to 25 m

Answer»

Given: V₁ = 7.5 MHz = 7.5 × 10⁶Hz,

V₁ = 12 MHz = 12 × 10⁶ Hz.

To find: Wavelength band

Formula: λ = \(\frac{c}{v}\)

Calculation: From formula,

V₁ = \(\frac{3\times10^8}{7.5\times10^6}\) = 40 m

V₁ = \(\frac{3\times10^8}{12\times10^6}\) = 25 m

∴ Wavelength band = 40 m to 25 m
