How does refraction support the particle theory of light? ) Particles bounce off surfaces similar to the way in which a ball bounces off a wall. Light slows down and bends when it moves from a less dense to a more dense medium. Forces act on the particles to push or pull them from one medium to another. As light passes through an opening, it spreads out in all directions.

The correct answer is: Light slows down and bends when it moves from a less dense to a more dense medium.<br /><br />Refraction occurs when light passes from one medium to another with a different density, causing the light to change speed and direction. This phenomenon supports the particle theory of light because it demonstrates that light behaves as if it is composed of particles that are affected by the forces of the different media. The change in speed and direction of the light particles as they move between media is consistent with the particle theory, which states that particles are influenced by forces and can change their motion when interacting with other particles or surfaces.
