Question

Explaining Wave Speed through Different Media

Explain why the speed of light is lower than 
3.0 × 108 m/s as it goes through different media.

Answer 1

Step-by-step explanation:

In a vacuum, there are no atoms or particles that interfere with the path of light. However, in other media, the speed of light is lower than 3.0 × 108 m/s because the wave is continuously absorbed and re-emitted by each atom in its path. The differences in speed are due to the composition of the medium and the density of the particles in the medium.

Answer 2

Explain why the speed of light is lower than

3.0 × 108 m/s as it goes through different media.

--------------------

the molecules are forced to vibrate. that vib causes re emission. speed of emiited waves less than in vac.
