Two objects, object a and object b, need to be identified. object a's index of refraction is determined to be 1.77, and object b's index of refraction is determined to be 1.333. knowing this information, which of the following must be true? a. light can pass through object b faster than it can pass through object a. b. the optical density of object b is higher than the optical density of object a. c. the optical density of object a is lower than the optical density of object b. d. light can pass through object a faster than it can pass through object b.

Light can pass through Object B faster than it can pass through Object A.

Explanation:

When light enters in the medium denser than air it bends towards the normal. Thus, if light enters in the medium with higher refracting index it slows down.

So, when light can pass through object B faster than that of object A as object A has higher refracting index than object B.

Speed of light is inversely proportional to the optical density. Optical density is directly proportional to refracting index. So, for higher optical density refracting index is higher and the speed of light is less.

Hence, optical density of object A is higher than that of object B.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
