You need to write the question for the solution.
Add the question then only can get the answer
Yes the molecules
are all compressed together
Answer:
D. Wind and solar energy help save money and reduce air pollution.
Explanation:
The wavelength of the given wave is calculated through the equation,
λ = c/v
where λ is the wavelength,
c is the speed of light, equal to 3x10⁸ m/s, and
v is the frequency
Then, we substitute the known values to the equation,
λ = (3 x 10⁸ m/s)/(1280 x 10³/s)
λ = 234.375 m
The wavelength of the "am" radio station is 234.38 m.
