what is energy transmitted through matter
â¢ Most often its behavior is a combination of two or more of these. modes. â¢ Reflection - there is no change in the matter because of the radiant. energy that strikes it and it does not let the energy pass through it. (i.e. it is opaque to the radiant energy), then it reflects the energy. Reflection only changes the direction of the beam of radiant energy, not its wavelength or amplitude. â¢ Transmission - matter allows radiant energy to pass through it. unchanged. Again, there is no change in any of the properties of the. radiant energy.
