A photon is a tiny particle that comprises waves of electromagnetic radiation. As shown by Maxwell, photons are just electric fields traveling through space. Photons have no charge, no resting mass, and travel at the speed of light.

This word describes a particle of light. A photon is a unit of light that cannot be broken into smaller pieces. This particle is the tiniest possible packet of electromagnetic radiation.

Wave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave. It expresses the inability of the classical concepts “particle” or “wave” to fully describe the behaviour of quantum-scale objects.

Dual nature of matter is an important concept in JEE physics and is basically the study of different nature that a matter possesses or exhibits. Hence, the matter is said to possess dual nature, i.e., it has both the properties of a particle and as well as a wave. …

Wave-Particle Duality At this point, scientists had some experimental evidence (diffraction and interference) that indicated light was a wave and other experimental evidence (black body radiation and the photoelectric effect) that indicated light was a particle.

The dual nature of light means that, in some experiments, light behaves as a wave. In other experiments, light behaves as a particle. In 1801, Thomas Young shined light between two adjacent slits.

We say that light is an electromagnetic wave because light is an oscillation of electric and magnetic fields. higher energy and shorter wavelength than red light.

The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. All EM energy waves travel at the speed of light. No matter what their frequency or wavelength, they always move at the same speed.

Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.
