while the photon travels at light speed and a neutrino travel at just below light speed why then are photons stopped by an object and the neutrino can past through?
This is not such a silly question. The problem is your assumption that the speed of the particles is the relevant factor.Simon Peach said:while the photon travels at light speed and a neutrino travel at just below light speed why then are photons stopped by an object and the neutrino can past through?
Photons and neutrinos are both fundamental particles in the Standard Model of particle physics. Photons are particles of light and carry electromagnetic energy, while neutrinos are neutral particles that interact weakly with matter.
Photons and neutrinos differ in several ways. Photons have no mass, while neutrinos have a very small mass. Photons also have no electric charge, while neutrinos have no electric charge but do have a weak charge. Additionally, photons interact with matter through the electromagnetic force, while neutrinos interact weakly with matter.
Photons have properties such as energy, frequency, and polarization. Neutrinos have properties such as mass, spin, and flavor. Both particles also have a corresponding antiparticle.
Photons are detected through interactions with matter, such as through the photoelectric effect or Compton scattering. Neutrinos are detected through interactions with matter, such as through the weak force or through collisions with atomic nuclei.
Photons have a wide range of applications, including in communication technology, medical imaging, and solar energy. Neutrinos have applications in astrophysics, such as in studying the properties of stars and supernovae, and in particle physics experiments, such as in studying the properties of the weak force.
