# What produces an electromagnetic wave quizlet?

Contents

What produces an electromagnetic wave? An oscillating or accelerating electric charge. “The vibrating electric and magnetic fields regenerate each other to make up an electromagnetic wave which emanates from the vibrating charge.”

## What produces an electromagnetic wave?

Electromagnetic waves are produced whenever electric charges are accelerated. This makes it possible to produce electromagnetic waves by letting an alternating current flow through a wire, an antenna. The frequency of the waves created in this way equals the frequency of the alternating current.

## What are electromagnetic waves produced from quizlet?

Electromagnetic waves can be produced by vibrating, electrically charged particles. When the particles vibrate the electric field around it vibrates, too. The vibration of the electric field creates a vibrating magnetic field. The vibrations of the two fields together produce EM waves.

## How is electromagnetic wave produced and propagated?

The spark current oscillates at a frequency (ν), which is a characteristic of the circuit. … The changing magnetic field, in turn, induces an electric field so that a series of electrical and magnetic oscillations combine to produce a formation that propagates as an electromagnetic wave.

## How are electromagnetic waves produced Class 12?

Electromagnetic waves are produced by accelerating charged particle. When the charge moves with acceleration, both the magnetic and electric fields change continuously. This change produces electromagnetic waves. Accelerated charge is the source of energy of these waves.

## What are electromagnetic waves quizlet?

Electromagnetic Waves. a transverse wave that transfers electrical and magnetic energy. Electromagnetic Waves consist of. vibrating electric and magnetic fields that move through space at the speed of light. Electric Field.

## What is necessary to produce any electromagnetic radiation?

Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. … These electrons in these atoms are then in a high energy state.

## What vibrates to produce electromagnetic waves?

Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. … After a short period of vibrational motion, the vibrating electrons create a new electromagnetic wave with the same frequency as the first electromagnetic wave.

## What is a wave How is it produced?

Waves are created by energy passing through water, causing it to move in a circular motion. … Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.

## What are electromagnetic waves Class 12?

Electromagnetic waves are those waves in which electric and magnetic field vectors changes sinusoidally and are perpendicular to each other as well as at right angles to the direction of propagation of wave.
