1 answer:

8 0

Answer:Visible light communication (VLC) is a wireless method that uses light emitted by LEDs to deliver networked, mobile, high-speed communication similar to Wi-Fi, leading to the term Li-Fi. It can be used as standalone solution or in a supplementary role to radio-frequency (RF) or cellular network communication

What is the wavelength of a radio photon from an "am" radio station that broadcasts at 1120 kilohertz?

Alex73 [517]

The wavelength of the radio photon is 268 m.

Electromagnetic waves travel with the speed of 3×10⁸m/s in vacuum. The speed of a wave c is related to its frequency f and wavelengthλ as follows:

$c=f\lambda$

Thus the wavelength is given by,

$\lambda =\frac{c}{f}$

Substitute 3×10⁸m/s for c and 1120×10³Hz for f.

$\lambda =\frac{c}{f}\\ =\frac{3*10^8m/s}{1120*10^3Hz} \\ =267.8 m\\ =268 m$

Thus the wavelength of the radio photon from an AM station is 268 m

What is power, and what is its relationship to voltage and amperage?

kvasek [131]

The relationship between amperage, voltage, and power is that power equals the amperage quantity times the amount of voltage.

Power: is the amount of energy transferred or converted per unit time.
