Question

observation and result for the experiment "Total Internal Reflection in a Stream of Water"?

Answer 1

Answer:

Heyy!

Explanation:

Technical notes

1. For easier penetration of the bottle with a nail, heat the nail above a candle.
2. The hole should be wider that the width of the laser beam, so that no unwanted refraction occurs. Above that, the laser beam can pass through the stream of water and you should be able to see some points of refraction, which visualises the demonstrated phenomenon.
3. When filling the bottle, it is recommended to seal the hole and the bottle so that the water does not spill until the experiment is prepared.
4. The effect can be improved by adding a few drops of milk into the water, which makes the laser beam more visible.

Pedagogical notes

1. In this experiment, not only the reflection of the laser beam occurs. There is also a refraction of the beam out from the water stream; otherwise we would not be able to see the beam.

Hope it helps!

Answer 2

Hi buddy

Here is your answer

Total internal reflection will not take place unless the incident light is traveling within the more optically dense medium towards the less optically dense medium. TIR will happen for light traveling from water towards air, but it will not happen for light traveling from air towards water.

As the stream of water begins to fall as a projectile along a parabolic path to the ground, the laser light becomes trapped within the water due to total internal reflection
