Final answer:
An electromagnetic wave with a frequency of 6.20 MHz has a wavelength in vacuum of approximately 48.4 meters.
Step-by-step explanation:
An electromagnetic wave with a frequency of 6.20 MHz has a wavelength in vacuum of approximately 48.4 meters.
Using the equation c = fλ, where c is the speed of light (3 x 10^8 m/s), we can rearrange the equation to solve for λ:
λ = c / f
Substituting the given values:
λ = 3 x 10^8 m/s / 6.20 x 10^6 Hz
Calculating the result:
λ ≈ 48.4 m
