If the electromagnetic radiation used to send television signals have a frequency of 3.0 * 10^9 Hz, what is its wavelength?

I forget how to do a problem like this. Just taking a guess, is this somewhat a conversion equation?

c = freq x wavelength.

c = 3E8 m/s
freq is given.
Solve fopr wavelength.

Just trying to understand this, but is C always the basic number when doing problems like this?

Always the answer would be .1, right?

Yes, you're correct! To find the wavelength of electromagnetic radiation, you can use the equation that relates the speed of light (c), frequency (f), and wavelength (λ). The equation is:

c = f * λ

where c is the speed of light, which is approximately 3.0 * 10^8 meters per second (m/s).

To find the wavelength, rearrange the equation:

λ = c / f

Plugging in the values you have:
f = 3.0 * 10^9 Hz

Substituting those values into the equation:

λ = (3.0 * 10^8 m/s) / (3.0 * 10^9 Hz)

Now, let's simplify the expression:

λ = (3.0 * 10^8) / (3.0 * 10^9) * m/s / Hz

Using the rules of exponents:

λ = 10^-1 * m = 0.1 meters = 10 cm

Therefore, the wavelength of the electromagnetic radiation used to send television signals with a frequency of 3.0 * 10^9 Hz is approximately 10 centimeters.
