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?
Answer
Answer: The image with diamond
Explanation:
Step1: Recall refractive index concept
The speed of light changes more when the refractive - index difference between the two media is larger.
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. The refractive - index difference between air and diamond is the largest among the given pairs. So, the speed of light changes the most when light passes from air to diamond.
