Question

A vHF television station assigned to channel 7 transmits its signal using the radio waves with a frequency 174MHZ calculate the wavelength of the radio waves be sue your answer has the correct number of significant digits

Answer 1

To calculate the wavelength of the radio waves, we can use the equation:

wavelength = speed of light / frequency

First, we need to convert the frequency from megahertz (MHz) to hertz (Hz).

174 MHz = 174 million Hz = 174 x 10^6 Hz

The speed of light is approximately 3 x 10^8 meters per second.

Now we can calculate the wavelength:

wavelength = (3 x 10^8 m/s) / (174 x 10^6 Hz)

wavelength = 1.72413793 meters

Since the frequency measurement has 3 significant digits, the wavelength should also have 3 significant digits. Therefore, the wavelength is approximately 1.72 meters.
