Do radio waves follow navigational rhumb lines?

Do radio waves follow navigational rhumb lines?

• A. True
• B. False
• C. Not enough information
• D. Sometimes

Answer: (B)

Radio waves propagate along straight-line paths in a uniform medium, while navigational rhumb lines are lines of constant bearing used for plotting courses on charts. A radio signal travels in space according to geometry and the medium’s refractive properties, not by maintaining a fixed compass direction relative to true north. In the atmosphere, refraction can bend the path, and at long ranges signals may reflect or refract, but these paths are not rhumb lines. So the statement is false.
