they are formed when a electric field and a magnetic field couple.
When ever a charged particle undergoes an acceleration it emits electromagnetic radiation. Therefore when an electron 'jumps' from a high energy quantum state to a lower energy quantum state it produces em radiation of a particular frequency.
And, more precisely, EM waves are created by accelerating a charge. An electron at rest (or cruising at constant speed) has a stable electric field radiating outwards (really inwards for negative charge). If the electron is accelerated, a ripple in the field radiates outward with the speed of light, with the strongest effect perpendicular to the electron's vector of acceleration and weakest part (zero) along the vector. The electric field fluctuation is in any plane along the vector, and the magnetic part is in the plane perpendicular to that and the vector.

The transfer of energy by electromagnetic waves?
The waves that are the most infictint are the seismic waves
1 What types of waves are light and electromagnetic waves?
The type of waves that are electromagnetic are the visible light waves
How do raidiators in homes transfer heat?
Radiators transfer heat by electromagnetic waves. The sun waves/rays send electromagnetic waves.
How are em waves different from mechanical waves?
mechanical waves need a medium to travel through, electromagnetic waves do not. Electromagnetic waves can travel through space, mechanical waves can not.:PElectromagnetic waves do not require a medium, but mechanical waves do.
Can electromagnetic spectrum waves travel through air?
Yes. Electromagnetic spectrum waves reach your eye through the air.
How are electromagnetic waves formed by the vibrations of particles?
Electromagnetic waves are formed when charged particles, such as electrons, vibrate or accelerate. These vibrations create changing electric and magnetic fields that propagate through space as waves.
How are electromagnetic waves formed when 4 hydrogen atoms fuse into 1 helium atom?
light waves are produced by our star. they are electromagnetic waves. please explain.
How are radio waves formed?
Radio waves are a type of electromagnetic radiation that are emitted by accelerating electric charges. When electrons within an antenna are oscillated or accelerated, they create electromagnetic waves at radio frequencies. These waves then propagate through space and can be received by devices like radios or antennas.
How does black hole tunnel formed?
Black hole tunnel is formed by strong electromagnetic waves moving in a rythmic way.
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
How are electromagnetic waves transfered?
Electromagnetic waves are transferred by electromagnetic radiation.
Are suns rays mechanical waves or electromagnetic waves?

What is the difference between electrmagnetic waves and lasers?
Electromagnetic waves are generated through frequency oscillations which usually involve a coil of wire or in an extension such as a transmitting antenna. Lasers are light, formed in a coherent beam and generally don't exhibit electromagnetic waves.
What type of energy is carried by electromagnetic waves?
Electromagnetic waves carry electromagnetic energy.
How are waves transferred?
Electromagnetic waves are transferred by electromagnetic radiation.
