Electromagnetic Waves.
Electromagnetic Waves.
Electromagnetic waves have both electrical and magnetic properties. These waves result from the oscillation of electric and magnetic fields perpendicular to each other and are able to travel through a vacuum. Examples of electromagnetic waves include light, radio waves, microwaves, and X-rays.
Electromagnetic waves are transverse (unpolarized or polarized) or circularly polarized waves that have some electrical properties and some magnetic properties. An electromagnetic wave consists of changing electric and magnetic fields. The repeated cyclic transfer of energy from the electric field (weakening it) to the magnetic field (strengthening it) until the electric field is gone, then from the magnetic field (weakening it) to the electric field (strengthening it) until the magnetic field is gone every cycle is the process by which electromagnetic waves propagate without requiring a medium (and is described in Maxwell's Equations).

Microphones will convert sound waves into electrical signals. An ear (i..e human ear) will also convert sound waves into electrical signals.
A fuzzy crackling sound will be heard because some of the electrical waves are still being transformed into sound waves.
A microphone uses sound waves, which are mechanical waves, to convert sound into an electrical signal. This electrical signal can then be amplified and transmitted. Electromagnetic waves, such as radio waves or light waves, are not used directly by a microphone in this process.
Examples of the characteristics of matter: state of matter, density, radioactivity, thermal properties, electrical properties, optical properties, chemical composition, etc.

Some common questions about the electromagnetic spectrum that can help us understand its properties and behaviors include: How do different wavelengths of electromagnetic waves affect their energy and frequency? What is the relationship between the speed of electromagnetic waves and the medium through which they travel? How do electromagnetic waves interact with matter, such as absorption, reflection, and transmission? How do different types of electromagnetic waves, such as visible light, radio waves, and X-rays, differ in their properties and applications? How are electromagnetic waves used in technologies like communication, imaging, and remote sensing?
A microphones sole function is to convert analogue air pressure waves into equivalent electrical waves for the purpose of recording or converting to digital those electrical waves. Some have minor additional functions such as low pass filter's, preamps, and spit balls (to prevent cymbalism and puffing).
Metalloids have some properties similar to properties of non metals; metalloids have bad thermal and electrical conductivity, they are brittle, soft etc.
