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:

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

answer: 5100 just subtract
