What do you know about Photons?

Explanation
Gilbert Lewis is credited with discovering the photon. He proposed the concept of the photon in 1926 while studying the behavior of light and its interaction with matter. Lewis's work on the photon helped to advance our understanding of quantum mechanics and the wave-particle duality of light. His discovery laid the foundation for further research and developments in the field of physics.

Explanation
The mass of a moving photon is given by the equation E=mc^2, where E is the energy, m is the mass, and c is the speed of light. Since photons have energy but no rest mass, their mass is zero. Therefore, the correct answer is "zero".

Explanation
Light is made up of photons. Photons are particles of light that carry energy and electromagnetic radiation. They have zero mass and travel at the speed of light. When an atom releases energy, it does so in the form of photons, which can then travel through space as electromagnetic waves. These photons can be absorbed or emitted by atoms, causing various interactions and phenomena such as reflection, refraction, and absorption. Therefore, photons are the fundamental particles that make up light.

Explanation
Photons are bundles of electromagnetic energy. Photons are particles of light, and light is a form of electromagnetic radiation. Electromagnetic energy refers to the energy carried by electromagnetic waves, which include visible light, infrared radiation, ultraviolet radiation, X-rays, and radio waves. Photons have no mass and travel at the speed of light. They carry energy and interact with matter, such as when they are absorbed or emitted by atoms. Therefore, the correct answer is electromagnetic energy.

Explanation
As the wave's frequency rises, the photon's energy increases. This is because the energy of a photon is directly proportional to its frequency. A higher frequency means that the photon has more energy. This relationship is described by the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the wave. Therefore, as the frequency increases, the energy of the photon also increases.

Explanation
The letter "h" in the equation E = hv represents Planck's constant. Planck's constant is a fundamental constant in quantum mechanics that relates the energy of a photon (E) to its frequency (v). It is denoted by the symbol "h" and has a fixed value of approximately 6.626 x 10^-34 joule-seconds. The equation E = hv shows that the energy of a photon is directly proportional to its frequency, with Planck's constant acting as the proportionality constant.

Explanation
Einstein developed the concept of photons. Photons are particles of light that carry energy and have properties of both particles and waves. Einstein's work on the photoelectric effect in 1905 led to the understanding that light is made up of discrete packets of energy called photons. This concept revolutionized the field of physics and laid the foundation for the development of quantum mechanics.

Explanation
Photons are elementary particles that make up electromagnetic radiation, including visible light. They have no mass, meaning they are massless. Additionally, photons have no electric charge, making them electrically neutral. Finally, photons are stable particles, meaning they do not decay or break down over time. Therefore, the correct answer is "all of the above" as all the statements are true for photons.

Explanation
The possible polarization states of a photon in a vacuum are linear polarization, circular polarization, and elliptical polarization. Linear polarization refers to the photon's electric field oscillating in a single plane, while circular polarization means the electric field rotates in a circular motion. Elliptical polarization occurs when the electric field traces an elliptical path. Therefore, the correct answer is 2, as it represents one of the possible polarization states of a photon in a vacuum.

Explanation
The energy and momentum of a photon are solely dependent on its frequency. This is because the energy of a photon is directly proportional to its frequency, according to the equation E = hf, where E is energy, h is Planck's constant, and f is frequency. Similarly, the momentum of a photon is also directly proportional to its frequency, according to the equation p = hf/c, where p is momentum and c is the speed of light. Therefore, the correct answer is frequency.
