Question

The dial on an FM radio contains numbers ranging from about 88 to about 108. These numbers correspond to the frequency of the radio station as measured in megahertz. What is the corresponding range of wavelengths? (Enter your answers from smallest to largest.)
from m to m The dial on an FM radio contains numbers ranging from about 88 to about 108. These numbers correspond to the frequency of the radio station as measured in megahertz. What is the corresponding range of wavelengths? (Enter your answers from smallest to largest.)
from m to m

Explanation / Answer

C=frequency x wavelength

C=3x10^8m/s

88MHz=88x10^6Hz                  Wavelength(m)=C/f           Wavelength(m)=3x10^8 / 88x10^6   = 3.409m

108MHz=108x10^6Hz             Wavelength(m)=C/f           Wavelength(m)=3x10^8 / 108x10^6 = 2.77m

Answers smallest to largest:          2.77m to 3.409
