Answer:

The wavelength is 4.55 m.

Explanation:

Given data

  • Frequency (ν): 66.0 MHz = 66.0 × 10⁶ Hz = 66.0 × 10⁶ s⁻¹
  • Speed of light (c): 3.00 × 10⁸ m/s
  • Wavelength (λ): To be found

We can determine the wavelength of the radio waves using the following expression.

c = λ × ν

λ = c / ν

λ = (3.00 × 10⁸ m/s)/66.0 × 10⁶ s⁻¹

λ = 4.55 m
