Wave or a Stream of Particles
Particles
Electromagnetic radiation can behave either as a wave or a particle. A wave particle is duality. Electromagnetic energy results from acceleration of a charge EM radiation can travel through a medium or vacuum.
Electromagnetic radiation sometimes behaves like waves - for example, interference.
Electromagnetic radiation is a form of energy that travels in waves and does not require a medium to propagate. It has characteristics such as wavelength, frequency, amplitude, and speed. These characteristics determine how electromagnetic radiation behaves, including how it interacts with matter, how it is absorbed or reflected, and how it can be used in various applications such as communication, imaging, and energy generation.
A photon is a fundamental particle of light that carries electromagnetic energy and behaves as both a particle and a wave. It has no mass and travels at the speed of light. Photons are the basic unit of all electromagnetic radiation, including visible light, radio waves, and X-rays.
Gamma rays is powerful, high frequency (1019Hz and above) electromagnetic radiation and behaves like the rest of the spectrum. Electromagnetic radiation has some of the properties of both particles, electric and magnetic fields.
Electromagnetic radiation is carried by electromagnetic waves.
The common definition of 'light' (visible) is electromagnetic radiation visible to the human eye. It is only a small part of what is known as the 'electromagnetic spectrum' - which is the range of wavelengths of all possible electromagnetic radiation. Light is electromagnetic radiation, as reported. But, even though it behaves like a wave, it also behaves as a particle. We can call a particle of light a photon. Light has two identities, a "duality" of sorts, that is called wave-particle duality. That's about as simple as it can get. Light is called a "wavicle" by some, and for reason that it displays qualities of both a wave and a particle.
Electromagnetic radiation, such as visible light or radio waves, does not have mass since it consists of massless particles called photons. These photons do not have an electric charge either but can carry energy and momentum.
The smallest amount of energy that can be emitted or absorbed as electromagnetic radiation is a photon, which behaves like a particle carrying discrete energy. This minimum amount of energy is determined by the frequency of the radiation, according to Planck's equation E=hf, where E is energy, h is Planck's constant, and f is frequency.
The packet of electromagnetic radiation is the photon.
Electromagnetic radiation is transferred by electromagnetic waves. Electromagnetic radiation is a fundamental phenomenon of electromagnetism.
