Question

1. radio waves travel at a speed of 300,000,000 m/s. wfnx broadcasts radio waves at a frequency of 101,700,000 hertz. what is the wavelength of wfnxs radio waves?

Explanation:

Step1: Recall the formula

The formula relating speed ($v$), frequency ($f$), and wavelength ($\lambda$) of a wave is $v = f\lambda$. We can rearrange it to find $\lambda=\frac{v}{f}$.

Step2: Substitute the values

Given $v = 300000000\ m/s$ and $f=101700000\ Hz$.
Substitute into the formula: $\lambda=\frac{300000000}{101700000}$.

Step3: Calculate the result

$\lambda=\frac{300000000}{101700000}\approx 2.95\ m$.

Answer:

The wavelength of WFNX's radio waves is approximately $2.95\ m$.
