Question

Which statement is most accurate

Answer 1

Answer:

Statement 2: The more optically dense the material, the higher the refractive index

Explanation:

The optical density of the material is different than the physical density of the material. Physical density is mass per unit volume. Whereas optical density of a material is the tendency of its atoms to absorb the energy of incident photons, maintain that in the form of vibrating electrons and then re emitting it as a new Electro-magnetic disturbance.

Higher the optical density, lesser will be speed of light in the medium and refractive index will be higher as it is related to speed of light in the medium as

$n_{medium} = \frac{3\times 10^{8}}{v_{medium}}$

Where,

n = refractive index of the medium

v = speed of light in the medium in m/s

Answer 2

Answer:

B. The more optically dense the material, the higher the refractive index.
