A photon is considered to have?
Correct answer: D. All of these
- A. Energy
- B. Wavelength and frequency
- C. Momentum
- D. All of these
Explanation
Option Dis correct.1.A photon is considered to have energy. The energy of a photon is given by the following equation: E = hν where: h is Planck's constant ν is the frequency of the photon2. A photon is considered to have both wavelength and frequency. This is because a photon is a quantum of light, and light is a wave. The wavelength of a photon is the distance between two consecutive peaks of the wave, and the frequency of a photon is the number of waves that pass a point in a given time. The wavelength of a photon is given by the following equation: λ = h/p where: λ is the wavelength of the photon h is Planck's constant p is the momentum of the photonThe frequency of a photon is given by the following equation: ν = c/λ where: ν is the frequency of the photon As you can see, the wavelength and frequency of a photon are inversely proportional. This means that as the wavelength of a photon increases, the frequency decreases, and vice versa.3.A photon is considered to have momentum. This is because photons carry energy, and energy is equivalent to momentum. The momentum of a photon is given by the following equation: p = h/λ where: p is the momentum of the photon h is Planck's constant λ is the wavelength of the photon The momentum of a photon is inversely proportional to its wavelength. This means that photons with shorter wavelengths have higher momenta.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
