The amplitude modulated (AM) radio wave bends appreciably round the corners of a 1 m × 1 m board but the frequency modulated (FM) wave only negligibly bends. If the average wavelengths of AM and FM waves are λa and λf.
A. λa > λf
B. λa = λf
C. λa < λf
D. we don’t have sufficient information to decide about the relation of λa and λf.
The wave with a higher wavelength bends the most. Hence, option (a) is the correct answer.
