Question

Refractive index of ethanol is 1.361 and it is known that benzene is optically dense than ethanol. Which could be the refractive index of benzene:

(a) 1.350

(b) 1.281

(c) 1.33

(d) 1.501​

Answer 1

Answer:

1.33 is the correct answer

Answer 2

Answer:

The correct option for this question is option d) 1.501

Explanation:

The refractive index is the ratio of the velocity or the speed of light in a vacuum as the first medium to the speed of light in another or the other medium. It is usually taken into consideration while we differentiate between the optically denser and optically rarer mediums. A higher or the greater refractive index value means that the medium is optically denser and vice versa. In the above problem, it has been mentioned that benzene is more optically denser than ethanol therefore its refractive index will also be greater than it. Hence only one of the given four values is greater than 1.361 which is option d) 1.501 hence option d is correct.
