  In this paper, we study a photon, a massive charged particle, and a massive
neutrino passing through matter. The hypothetical left-right symmetric weak
interaction, which is used in Wolfenstein's equation can generate the resonance
enhancement of neutrino oscillations in matter, which disappears when neutrinos
go out into vacuum from matter (the Sun). It is shown that since standard weak
interactions cannot generate masses, the laws of conservation of the energy and
the momentum of neutrino in matter will be fulfilled only if the energy $W$ of
polarization of matter by the neutrino or the corresponding term in
Wolfenstein's equation, is zero. This result implies that neutrinos cannot
generate permanent polarization of matter. This leads to the conclusion:
resonance enhancement of neutrino oscillations in matter does not exist. It is
also shown that in standard weak interactions the Cherenkov radiation cannot
exist.
