Answer:
And if we convert to megahertz we got:
Step-by-step explanation:
For any mechanical wave we have the following general relationship:
where:
v represent the speed of the wave = 299790000 m/s
represent the wavelength for the radio station
f represent the frequency of interest
If we solve for the frequency we got:
And replacing the values we got:
And if we convert to megahertz we got:
