Description

Here in this physics quiz, we shall study electromagnetic waves. Our main focus will be on the electromagnetic spectrum and its characteristics. It’s been seen that the arrangement is done with respect to frequency and wavelength. There are a lot of other concepts on the electromagnetic spectrum covered in this quiz.

Electromagnetic waves, often referred to as EM waves are waves that result from vibrations between an electric field and a magnetic field. They are formed when an electric field comes in contact with a magnetic field, and these two fields are always perpendicular to each other. EM waves travel at the speed of light (3.00x10^8 m/s) in a vacuum and are neither deflected by an electric field nor a magnetic field. However, they can be diffracted. They don't need any medium for their transmission because they can travel through anything be it a solid material, air, or in a vacuum. One important fact about EM waves is that they are transverse waves, meaning their measurements are done by their amplitudes and wavelengths.

EM waves sound interesting, right? Take this quiz in order to discover a lot more about this section of physics. Good luck as you answer the quiz.
