<h3><u>
What are electromagnetic radiations?</u></h3>
- The electromagnetic (EM) field's waves, which are travelling through space and carrying electromagnetic radiant energy, make up electromagnetic radiation (EMR).
- It consists of X-rays, gamma rays, microwaves, infrared, visible light, ultraviolet, and radio waves.
- These waves are all a component of the electromagnetic spectrum.
- Electromagnetic waves, which are synchronized oscillations of the electric and magnetic fields, are the traditional form of electromagnetic radiation.
- Due to the periodic alteration of the electric or magnetic field, electromagnetic radiation or waves are produced.
- Different wavelengths of the electromagnetic spectrum are created depending on the manner in which this periodic change takes place and the power generated.
Electromagnetic waves move at the speed of light, typically abbreviated as c, in a vacuum.

Maslow's hierarchy of needs is a theory in psychology that argues that the human needs are organized in a hierarchy, having to be fulfilled on a crescent level, a lower level must be completely satisfied and fulfilled before moving onto a higher pursuit.
The five levels are Physiological needs; Safety Needs, Social belonging; Self-Esteem and Self-actualization.
Thus, Self-actualization is the highest level, being summarized in the sentence: "What a man can be, he must be."
