Answer
Given,
Wavelength of FM radio station = 3.387 m
We know that,
1 m = 3.2808 ft
now, converting wavelength of the FM radio station into ft.
3.387 m = 3.387 x 3.2808
= 11.11 ft
Hence, the wavelength of the of the FM radio station is equal to 11.11 ft.
Significant figure of the of the answer is equal to = 4
