Light can be considered as a wave, or as a particle. As a particle, the particles are called photons. As a wave, light is an electromagnetic wave. In either case, the speed of light (in a vacuum) is approximately 300,000 km/sec.
The speed of a photon is the same as the speed of an electromagnetic wave, which is the speed of light in a vacuum, approximately 299,792 kilometers per second. Photons are the fundamental particles that make up electromagnetic waves, such as visible light, radio waves, and X-rays.
When the frequency of an electromagnetic wave is doubled, its energy and wavelength remain the same but its photon energy increases. This higher frequency wave will have shorter oscillation periods and carry more energy per photon compared to the original wave.
A particle of light. Or, in general, of an electromagnetic wave.
The wave number of a photon is the spatial frequency of the photon's electromagnetic wave. It is defined as the reciprocal of the wavelength of the photon, typically measured in units of inverse meters. As the wave number increases, the wavelength decreases, and vice versa.
The speed halves.

In air at sea level, the speed of electromagnetic waves isroughly 882 thousand times the speed of sound.

A photon is a discrete bundle of electromagnetic energy, carrying a specific amount of energy and momentum. Photons do not have mass and travel at the speed of light in a vacuum. They exhibit both wave-like and particle-like properties.

Photons are fundamental particles of light that have no mass, but they do have energy and momentum. They travel at the speed of light in a vacuum and exhibit both wave-particle duality, meaning they can behave as both a wave and a particle. Photons also carry electromagnetic force and are responsible for electromagnetic interactions.
As frequency increases in an electromagnetic wave, the photon energy increases, not decreases. This is because photon energy is directly proportional to the frequency of the electromagnetic wave, as described by Planck's equation E=hf, where E is energy, h is Planck's constant, and f is frequency.
An electromagnetic wave in space does not slow down because there is no medium for it to interact with and lose energy to. In vacuum, the wave travels at the speed of light (c) as specified by Maxwell's equations.
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.
Actually, a gamma ray is a high-energy photon, not a particle. It is electromagnetic radiation emitted from the nucleus of an atom during radioactive decay or in other nuclear processes. Gamma rays have no charge and no mass.
