A level Electromagnetic Spectrum Quizzes

 Revising A level Electromagnetic Spectrum with quizzes:

(Simple A level Electromagnetic Spectrum quizzes to teach students at the A level preparing for GCE, GCSE and necta.)

In this section, we will be looking at the electromagnetic spectrum. This area is very important when it concerns physics. To look at it in detail, practice quizzes are made available below for you. But before we proceed, let's have a recap of what the electromagnetic spectrum is:

In a branch of physics known as classical physics, the flow of energy at the speed of light through a vacuum or through a material medium is in the form of the electric and magnetic fields, and they make up electromagnetic waves such as radio waves, visible light, and gamma rays. In such a wave, electric and magnetic fields are mutually linked with each other at right angles and perpendicular to the direction of motion. Hence:

 The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies.  The electromagnetic spectrum is a term used by scientists to describe the whole range of light that exists. From radio waves to gamma rays, most of the light in the universe is invisible to us! Light is a wave of alternating electric(E) and magnetic(B) fields. The human eye can only detect only a small portion of the electromagnetic spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion.

When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy. We depend on this energy every hour of every day. Without it, the world you know could not exist.

 During exams, students are evaluated via multiple-choice and/or short answer questions on the electromagnetic spectrum. The concept must be understood in order to get a pass in questions under it. In this light, many practice quizzes are made available Click here for more entertaining quizzes.

This platform is one of the best you'll find, with relative ease in practicing for your exams. For more info, visit gcequiz.com. Enjoy yourself.
