8. My favorite radio station is NPR, which transmits a signal that Is has a wavelength d 3.22 m. What is the fraquency of this signal? Remember, light speed k(3times 10^8m/s.)

Here's how to calculate the frequency of the NPR signal:<br /><br />**1. Recall the relationship between wavelength, frequency, and the speed of light:**<br /><br />The formula is: speed of light (c) = wavelength (λ) * frequency (f)<br /><br />**2. Plug in the known values:**<br /><br />* c = 3 x 10⁸ m/s (speed of light)<br />* λ = 3.22 m (wavelength)<br /><br />**3. Solve for frequency (f):**<br /><br />f = c / λ<br />f = (3 x 10⁸ m/s) / 3.22 m<br />f ≈ 9.32 x 10⁷ Hz or 93.2 MHz<br /><br />**Answer:** The frequency of the NPR signal is approximately 93.2 MHz.<br />
