select the correct image. the speed of light changes as it passes from one medium to the next. in which image does the speed of light change the most? air water air glass air diamond reset next
Answer
Explanation:
Step1: Recall refractive index concept
The greater the refractive - index difference between two media, the more the speed of light changes. The refractive index of air is approximately 1, water is about 1.33, glass is about 1.5 - 1.6, and diamond is about 2.42.
Step2: Compare refractive - index differences
When light passes from air to water, the refractive - index difference is $\Delta n_{air - water}=1.33 - 1 = 0.33$. When it passes from air to glass (taking an average refractive index of 1.55), $\Delta n_{air - glass}=1.55 - 1 = 0.55$. When it passes from air to diamond, $\Delta n_{air - diamond}=2.42 - 1 = 1.42$.
