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 type of waves that are electromagnetic are the visible light waves
The waves that are the most infictint are the seismic waves
Radiators transfer heat by electromagnetic waves. The sun waves/rays send electromagnetic 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.
Yes. Electromagnetic spectrum waves reach your eye through the air.
light waves are produced by our star. they are electromagnetic waves. please explain.
Electromagnetic waves
Black hole tunnel is formed by strong electromagnetic waves moving in a rythmic way.
Radio waves ARE electromagnetic waves.
Electromagnetic waves are transferred by electromagnetic radiation.
first of all electromagnetic waves are energy waves. and we call electromagnetic waves RADIATION.

Electromagnetic waves transfer energy.
electromagnetic waves
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.
Electromagnetic waves are transferred by electromagnetic radiation.
