An FM radio station found at 103.1 on the FM dial broadcasts at a frequency of 1.031 × 108 s−1 (103.1 MHz). What is the wavelength of these radio waves in meters?

λ=2.9m

Explanation:

given                              required                    solution

f=1.031×10**8/s               λ=?                        λ=c/f

c=3×10**8m/s                                                λ=3×10*8m/s/1.031×10*8

                                                                           λ = 2.9m

b

explanation:

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
