Video 1: 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 do not know. I have not idea.

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.**__

Slit is a verb and noun.

slit ( slit )

transitive verb [|slit] ,  [|slitting] slit′·ting noun http://www.yourdictionary.com/slit
 * 1) to cut or split open, esp. by a straight, lengthwise incision
 * 2) to cut lengthwise into strips
 * 3) to cut (//off//); sever
 * 1) a cut or tear, esp. one that is long and straight
 * 2) a long, narrow opening or crack

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

Slit, experiment,theory.process, cut

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

Yes, slit, experiment.

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


 * a.What does he need to do the experiment?
 * 1) Little balls of matter,
 * 2) A machine to shoot balls,
 * 3) Electrons,
 * 4) Electron machine to shoot electrons,
 * 5) Water,
 * 6) Two tables, one with a slit and the other with two slits,
 * 7) A wall.


 * b.How many steps does it have?

The experiment has three steps.

in the first step, Dr. Quantum shoots the balls through a table with one slit and a table with two slits, and noted that are reflected in a vertical line and two vertical lines respectively. in the second step looks at what happens when the waves passing through a table with one slit and what happens when the waves passing through two slits. and finally makes the same process, but with electrons.
 * c.What happens in each step?


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

The third element are electrons.

**3. What happens with balls and one slit? And with two slits?**

when the ball passed through the a table with one slit reflected in a vertical line in the wall and when he uses the table with one slits, observed two vertical lines.

**4. What about waves?**

when he uses waves and one slit the result is a wave and reflected on the wall a vertical line and when he uses the table with two slits observed two waves and refleted several vertical lines. **5. What happens with electrons**

when he uses the table with one slit observed a vertical lines on the wall, but when he uses the table with two slit observed several vertical lines on the wall.

**6. What explanation does Dr. Quantum give?**

I'm not sure but I think it's because the electrons are separated into smaller particles and each of these particles form new waves.
