A certain radio station broadcasts at 1430 kilohertz. This is the frequency of oscillation of electrons in the transmitting antenna producing the radio wave. Find the period of the electrons' motion.

P=1/F = 1/1430=6.993*10^-4 Millisecondz

= 6.993*10^-7 Seconds.

To find the period of the electrons' motion, we need to use the formula:

Period (T) = 1 / Frequency (f)

Given that the frequency is 1430 kilohertz (kHz), we first convert it to hertz (Hz), as follows:

1 kilohertz (kHz) = 1000 hertz (Hz)

So, 1430 kilohertz (kHz) is equal to 1430 * 1000 hertz (Hz), which is equal to 1,430,000 hertz (Hz).

Now, we can find the period by substituting the frequency into the formula:

T = 1 / 1,430,000
T ≈ 7.0 x 10^-7 seconds

Therefore, the period of the electrons' motion in the transmitting antenna is approximately 7.0 x 10^-7 seconds.
