Does a single photon have 'color'? If so, what physical attribute(s) of the photon embody the Hubble velocity color shift?
A single photon is the smallest unit of light, also known as an elementary particle. It is the basic building block of all forms of electromagnetic radiation, including visible light.
No, a single photon does not have mass. It is considered a massless particle.
A single photon does not have a color in the traditional sense. It is a particle of light that can appear as different colors depending on its energy level. The color of a photon is determined by its wavelength, with longer wavelengths appearing as red and shorter wavelengths appearing as blue or violet.
No, a single photon can only have one color at a time. However, photons can exhibit behaviors of different colors, such as exhibiting wave-like properties for longer wavelengths and particle-like properties for shorter wavelengths.
The color of a single photon is measured by its wavelength, which can be detected using specialized equipment such as spectrometers or detectors. Scientists can also use the photoelectric effect to measure the energy of a single photon, which is directly related to its color.
