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
