Question

104.3 MHz (typical frequency for FM radio broadcasting) Express your answer using four significant figures.

Calculate the wavelength of each frequency of electromagnetic radiation: 104.3 MHz (typical frequency for FM radio broadcasting) Express your answer using four significant figures. 1080 kHz (typical frequency for AM radio broadcasting) (assume four significant figures) Express your answer using four significant figures. 835.6 MHz (common frequency used for cell phone communication) Express your answer using four significant figures.

Explanation / Answer

MHZ= 106 Hz, 104.3 HZ= 104.3*106 HZ

from =c, c= 300000*1000 m/se=3*108 m/se

= c/=2.876 m

when =1080KHZ= 1080*103 HZ, =3*108/ (1080*1000)=277.7788m

when =835.6MHZ=835.6*106Hz, =3*108/(835.6*106)=0.359 m
