Which statement best describes the relationship between an object's density and its index of refraction? As the tendency of the atoms to absorb energy before reemitting it increases, the refractive index increases.

As the mass per unit volume of the substance increases, the refractive index decreases.

As the physical density of the substance increases, the refractive index increases.

As the optical density increases, the refractive index decreases. The image shows an example of white light entering a prism and coming out as colors of the rainbow.

How does a prism produce the colors of the rainbow from white light?

by reflecting light with white wavelengths and transmitting light with colored wavelengths

by changing the wavelength of white light into other wavelengths

by absorbing colorless wavelengths from white light

by separating the light of different wavelengths

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

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.
