These tasks: ν (frequency of the specified electromagnetic waves) = 10,000 Hz = 10 ^ 4 Hz.
Constants: Ve (speed of electromagnetic waves) = C = 3 * 10 ^ 8 m / s.
The length of the indicated electromagnetic waves in the air is calculated by the formula: λ = Ve / ν.
Calculation: λ = 3 * 10 ^ 8/10 ^ 4 = 3 * 10 ^ 4 m = 30 km.
Answer: The length of these electromagnetic waves is 30 km.
