In the radio receiver, one of the VHF bands receives transmissions, the wavelength

In the radio receiver, one of the VHF bands receives transmissions, the wavelength of which is 35-45 m. Find the frequency range.

λ1 = 35 m.
λ2 = 45 m.
s = 3 * 10 ^ 8 m / s.
f1 -?
f2 -?
The wavelength λ and the frequency f are related by the formula for the propagation speed: c = λ * f.
f1 = s / λ1.
f1 = 3 * 10 ^ 8 m / s / 35 m = 0.0857 * 10 ^ 8 Hz.
f2 = s / λ2.
f2 = 3 * 10 ^ 8 m / s / 45 m = 0.0666 * 10 ^ 8 Hz.
Answer: f1 = 0.0857 * 10 ^ 8 Hz, f2 = 0.0666 * 10 ^ 8 Hz.
