Citizen's band (CB) radio utilizes frequencies between commercial AM and FM. What is the frequency of an 11.70 m wavelength CB channel?
MHz
To solve for MHz (megahertz), you need to convert the given wavelength from meters to the corresponding frequency in hertz, and then convert hertz to megahertz.
The formula to convert wavelength to frequency is:
Frequency = Speed of light / Wavelength
The speed of light is approximately 3 x 10^8 meters per second (m/s).
First, convert the given wavelength of 11.34 meters to frequency in hertz using the formula:
Frequency = 3 x 10^8 m/s / 11.34 m
Frequency = 26,456,066.37 Hz (approximately)
To convert hertz to megahertz, divide the frequency by 1,000,000 (since 1 megahertz is equivalent to 1,000,000 hertz):
Frequency in megahertz = 26,456,066.37 Hz / 1,000,000
Frequency in megahertz = 26.46 MHz (approximately)
Therefore, the frequency of an 11.34 m wavelength CB channel is approximately 26.46 MHz.
