3. what is the wavelength (in meters) of the electromagnetic carrier wave transmitted by the
sports fan radio station at a frequency of 640 x 109 hz?
with work

The wave with the frequency of 640 × 10⁹ Hz have 5 × 10⁻⁴ m wavelength.

Explanation:

Given data:

Frequency of wave = 640 × 10⁹ Hz

Wavelength = ?

Solution:

speed of light = 3 × 10⁸ m/s

Formula:

wavelength =Speed of light / frequency

λ =  c / f

Now we will put the values in formula.

λ =   3 × 10⁸ m/s /  640 × 10⁹ Hz

Hz = s⁻¹

λ =   3 × 10⁸ m/s /  640 × 10⁹ s⁻¹

λ =  5 × 10⁻⁴ m

The wave with the frequency of 640 × 10⁹ Hz have 5 × 10⁻⁴ m wavelength.

did you find the answer?

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
