Same
Less than that
greater than that
more​

Answer 1

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 in glass (refractive index of 1.5).

Answer 2

Answer:

The speed of light in glass is less than that in water

Explanation:

light travels in water is 225,000 km per second

light travels in glass is 200,000 km per second
