Based on the images seen here, identify which phase of matter would transmit light waves the fastest, and why? a) the gas would transmit the fastest because the particles move the fastest. b) the solid would transmit the fastest because the particles are closest together. c) the liquid would transmit the fastest because the particles are the most freely moving. d) the gas would transmit the fastest because there are the fewest particles to interfere with the waves.

The speed of light is fastest in gas because there are fewest particles to interfere with the waves. Light when strike from an object, its either bend/refract or reflect or absorb. In vacuum or space, when there is no particle to interfere, light travel in a straight path at fastest speed.

answer would be d.) i hope this

explanation:

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
