What is the condition of roughness of earth for earth to be electrical

1.	What is the condition of roughness of earth for earth to be electrically smooth?(a) R < 0.1(b) R > 10(c) R > 0.1(d) R > 1I got this question in examination.The above asked question is from Radio Wave Propagation topic in section Radio Wave Propagation of Antennas
Answer» The correct ANSWER is (a) R < 0.1 To explain: Earth is CLASSIFIED as electrically SMOOTH and electrically rough. If the ROUGHNESS of earth R < 0.1, then it is electrically smooth. If the roughness of earth R > 10, then it is electrically rough.
