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.
