Question

7. The amplitude modulated (AM) radio wave
bends
appreciably round the corners of a 1 mx1 m board but
the frequency modulated (FM) wave only negligibly
bends. If the average wavelengths of AM and FM waves
are 2a and are
(a) na > ar
(b) na = hf
(c) la <f
(d) we don't have sufficient information to decide about
the relation of na and .
8. Which of the following sources gives best monochromatic​

Answer 1

Answer:

The amplitude modulated (AM) radio wave bends appreciably round the corners of a 1 m x 1 m board but the frequency modulated (FM) wave only negligibly bends. If the average wavelengths of AM and FM waves are λ 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
