<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.

Part of Question completed :
Which basic principle of individual choice does Charles's plan illustrate that his wife's advice does not?
Many decisions are made on the margin.
People usually exploit opportunities to make themselves better off.
Resources are scarce.
All costs are opportunity costs.
Answer:
All costs are opportunity costs
Explanation:
All choices have opportunity costs. If Charles decides to swim, he gives up the time that he could have spent biking or running. The opportunity cost of an hour of swimming is therefore an hour of biking or running, whichever he believes has most value as an alternative which could justify the sacrifice of one hour for swimming alone. There is no information on the value of an extra hour swimming however so we cannot determine whether it is best for Charles to spend time equally on all sports or otherwise.
