It is observed that amplitude modulated (AM) radio wave shows appreciable diffraction when it encounters an opening of size 75 cm xx 75 cm. In such a case, diffraction shown by frequency modulated (FM) wave is very negligible. If lambda_A and lambda_F represent average wavelengths of AM and FM waves, then
