The energy of an electromagnetic wave is typically emitted in short bursts referred to as photons.
<h3>What is electromagnetic energy?</h3>
Electromagnetic energy can be defined as form of energy that is primarily carried by electromagnetic waves such as:
This ultimately implies that, an electromagnetic energy refers to a form of energy that typically moves as particles at the speed of light, which is about three hundred million meters per seconds (3 × 10⁸ m/s).
In conclusion, we can infer and logically deduce that the energy of an electromagnetic wave is typically emitted in short bursts referred to as photons.

The ph of the buffer solution given after 0.750 mol of H⁺ have been added is; 4.34
<h3>What is the PH of the Buffer?</h3>
pKa = -log(Ka) = 4.20
[A⁻] = [NaC₇H₅O₂]
[HA] = [HC₇H₅O₂]
Concentration of NaC₇H₅O₂ in the preferred buffer solution is;
[132.8g/(144.11 g/mol * 300 mol)] * 1000 mL/1 L = 3.07 M
Formula for the PH here is;
pH = pKa + log [A⁻/HA]
Thus;
pH = -log(6.3 x 10⁻⁵) + log [3.07/2.31]
pH = 4.34
