which of the following materials would cause light to slow down the most when passing through it? a air b water c glass d diamond
Answer
Explanation:
Step1: Recall refractive - index concept
The speed of light in a medium is inversely proportional to the refractive index of the medium. Higher refractive index means lower speed of light.
Step2: Compare refractive indices
The refractive index of air is approximately 1, water is about 1.33, glass is about 1.5 - 1.7, and diamond is about 2.42.
Answer:
D. Diamond
