Answer:

Best explains Jamming

Explanation:

<em>The deliberate radiation of electromagnetic (EM) energy to degrade or neutralize the radio frequency long-haul supervisory control and data acquisition (SCADA) communications links, best explains what?</em>

Jamming is defined as the blocking or interference with authorized wireless communications. it's a problem  in personal area network wireless technologies. Jamming can occur inadvertently due to high levels of noise .

Jammers can send radio signals to interfere or disrupt communication flows by by decreasing the signal-to-noise ratio.They use radio frequency to interfere with communications by keeping it busy.

What is the energy of a photon of light having a wavelength of 4.5 x 10-7 meters? (Planck’s constant is 6.626 x 10-34 joule seco
Ivenika [448]
The answer is <span>4.4143 x 10-19 joules
</span>
The energy (E) is: E = h * f
h - Planck's constant
f - the frequency

The frequency (f) is: f = c/∧
c - the speed of light
∧ - the wavelength

Hence:
E = h * f = h * c / ∧

We know:
h = 6.626 x 10⁻³⁴<span> Js
c = </span>2.998 x 10⁸<span> m/s
</span>∧ = 4.5 x 10⁻⁷<span> m

E = </span>6.626 x 10⁻³⁴ Js * 2.998 x 10⁸ m/s / 4.5 x 10⁻⁷ m 
E = 4.4143 x 10⁻³⁴ ⁺ ⁸ ⁻ ⁽⁻⁷⁾ J 
E = 4.4143 x 10⁻¹⁹ J
