Unreasonable ResultsTo save money on making military aircraft invisible to radar, an inventor decides to coat them with a nonreflective material having an index of refraction of 1.20, which is between that of air and the surface of the plane.This, he reasons, should be much cheaper than designing Stealth bombers. (a) What thickness should the coating be to inhibit the reflection of 4.00-cmwavelength radar? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?
