What do you think would happen if light traveled through material that had more particles than glass?
A.
Light would be slowed down more because it would bump into more particles
B.
Light would speed up because the particles would give it a push.
C.
Light doesn't change speed so it would move through without slowing down
A. Light would be slowed down more because it would bump into more particles.
A. Light would be slowed down more because it would bump into more particles.
To determine the answer, we can consider the behavior of light when it interacts with particles in a material. When light waves pass through a medium, such as glass or any other material, they interact with the particles of that material.
In general, light slows down when it passes through a medium. This is because the electric field of the light waves interacts with the charged particles in the material, causing them to oscillate. As a result, the wave propagation slows down.
Therefore, if we consider a material that has more particles than glass, the light would indeed be slowed down more. The increased number of particles would lead to a higher frequency of interactions, resulting in a greater reduction in the speed of light.
So, the correct answer is A. Light would be slowed down more because it would bump into more particles.
