Arrange the following materials in increasing order of refractive Index A. Diamond B. Water C. Air D. Vacuum Choose the correct answer from the options given below :
D, B,C, A
The question asks to arrange the given materials in increasing order of refractive index. The refractive index of a material is a measure of how much the speed of light is reduced inside the material compared to vacuum. Let's analyze the refractive indices of the materials provided:
- Vacuum: The refractive index of vacuum is 1, as it is the standard reference with no optical density.
- Air: The refractive index of air is approximately 1.0003, which is very close to 1 because air is not much denser than vacuum.
- Water: Water has a refractive index of about 1.33, as it is denser than air and therefore slows down light more.
- Diamond: Diamond has a refractive index of about 2.42, making it one of the highest for naturally occurring materials. This is due to its dense atomic structure.
Based on the refractive indices, the order from lowest to highest is:
- Vacuum (Refractive Index = 1)
- Air (Refractive Index ≈ 1.0003)
- Water (Refractive Index = 1.33)
- Diamond (Refractive Index = 2.42)
Therefore, the correct order is D, C, B, A. However, please note the options introduced a minor error in their sequence, the correct understanding should align with this factual data. Let's check the given options:
- A, C, B, D - This order is incorrect as it doesn't match the factual sequence of refractive indices.
- D, B, C, A - This order is incorrect. It suggests Water before Air, which is not correct.
- C, D, A, B - This order is incorrect as Air should come before Water.
- B, A, D, C - This order is incorrect as Diamond should come last due to its highest refractive index.
Considering this interpretation issue, check the factual sequence and assess the options available on intuition-based choices.
