can light travel in water ​

Sagot :

Answer:

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).

Explanation:

Answer:

No.

Explanation:

Light does not travel through water.
There is complete darkness beyond 100 m under the sea. Some wavelengths of light illuminate the upper layers of the sea and aid in photosynthesis through phytoplankton. But that’s it.

If light could have passed through water, we would have seen the bottom of oceans. Forget oceans, we cannot see the bottom of a river too.
