Question

how fast does the light travel in a glass of refractive indez is 1.5​

Answer 1

Explanation:

200,000 kilometers per second

Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index of 1.3; see Figure 2) and 200,000 kilometers per second inglass (refractive index of 1.5).
