The speed of radio waves can be approximated to be 299,790,000 meters per second. The wavelength of a particular radio station’s signal is 3.03 meters. What is the frequency, in millions of Hertz (megahertz), of this radio station? Round your answer to the nearest tenth of a megahertz.

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:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
