Need Help? Read It L Watch It i 2 points My Notes I SerPSE9 37 P033. FB. 3.40 cm and the index of refraction of the p A possible means for making an airplane invisible to radar is to coat the plane with an antireflective polymer. If radar waves have a wavelength of is n B 1.38 how thick would you make the coating? (Assume that the index of refraction of the plane is higher than that of the coating. Also assume that the radar waves are normal to the surface of the coating. Give the minimum thickness that would make the airplane invisible to radar.) Need Help? Read It Le Master It

Explanation / Answer

minimum thickness t = L/4n

where L = wavelength

t = 3.4cm/4* 1.38

t = 0.615 cm
