Video+1!

Great Job Francisco. Remember not to use contractions in formal speech Dr. Quantum - Double slit experiment === ** Before watching the video, answer the following questions: ** ===

1. You are about to watch a video called "Dr. Quantum - Double slit experiment". What do you think it will be about?

I think there should be some physical experiment, but I'm not sure. = = 2. Go to a dictionary and copy the definition of "slit". Is it a noun, a verb? Is it is both? Mention all definitions. __**Please acknowledge the source.**__

"A **slit** is a vertical or horizontal space that can open and close" ([])

A slit is a noun and a verb, in spanish this word means, something like "hendidura" or "abrir"

3. Mention five words you think you will find in the video

1) Physics

2) Slit

3) Double

4) Experiment

5) Space

=== **During and after watching the video, please answer ** ===

 * 1. Are there any of the words you mentioned in the previous question in the video? **

Yes, they are: Double, experiment, slit, physics

**2. What's the experiment about? Describe it.**

The experiment consist in show the diferents between how small particles, and infinitesimal particles, act passing through one or two slits.


 * a.What does he need to do the experiment?

Dr. Quantum, needs a trigger of particles, two walls: the first with just one slit and the second with two slits and the screen


 * b.How many steps does it have?

A total of sis steps, diveded in 3 parts.


 * c.What happens in each step?

1- Dr. Quantum uses particles, them were fired through a wall with one slit, hitting the screen and creating a band. Then the Dr. repeated this experiment with the same materials but changing the wall for one for to slits, the results show two bands.

2- Dr. Quantum have done his experiment with waves, and like the first experiment, he prove it with two walls, one has just a single slit, and the second has two. The wave hits the simple slit and radiate out making a band in the screen with a most intensity similar to the band that the particles has made. But whit the second wall with two slits, the waves that match can cancel one with each other, making an interference pattern.

3- Dr. Quantum tried to prove the same experiment but shutting electrons. So, when you have the first wall the electrons make a band just like if they were particles, but, whit two slits the electrons make an interference pattern like the waves.


 * d. What is the third element Dr. Quantum uses?

The third element that Dr Quantum use, are the electrons. Those are a tiny particle.

In the wall with one slit the balls made an band on the screen, and in the wall with two slits, they made a another band, a second band.

In the wall with one slit the waves made a band similar than balls, but in the wall with second slits, the waves hits the slits and radiate out, and the semi-circles cancel part of them with each other, making an interference pattern.

The electrons in the first case acts like if the were balls, so the electrons make a band. But in the second case the electrons made an interference patterns like if they were waves.

I'm not sure, I even think that Dr Quantum not have a explanation real, but he said that the electrons decides to act different like if the know that it is an observer trying to measure the result
