 * Great job 7pts **

** 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 don't know about it. ** **I haven't 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 noun and a verb. All definitions are the following: **
= **Verb:  **= =** 1. **** Slit is to make a straight long incision in; split open. **= =** 2. **** Slit is to cut into strips lengthwise. **= =** 3. **** Slit is to sever. **= =** Noun: **= =** 1. **** Slit is a long narrow cut. **= ==

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

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

** 2. What's the experiment about? Describe it. **
· a.What does he need to do the experiment? · b.How many steps does it have? · c.What happens in each step? · d. What is the third element Dr. Quantum uses? =** It is an electron. **= ** 3. What happens with balls and one slit? And with two slits? ** **** 4. What about waves? ** **** 5. What happens with electrons? **
 * The experiment is about the behavior of particles, waves and electrons, when they are crossing a slit and double slit. **
 * He needs to have particles, waves, electrons and an observer what can see the behavior of the elements when they are crossing a slit and double slit. **
 * There are six steps. **
 * The steps are the following: **
 * 1-. He does to cross the particles through a slit. **
 * 2-. He does to cross the particles through a double slit. **
 * 3-. He does to cross the waves through a slit. **
 * 4-. He does to cross the waves through a double slit. **
 * 5-. He does to cross the electrons through a slit. **
 * 6-. He does to cross the electrons through a double slit. **
 * When he uses balls and one slit then the result is a vertical line, while with two slits the result is two vertical lines.
 * When he uses waves and one slit then the result is a point, it reflects a vertical line, while with two slits the result is a set of points, they reflect some vertical lines.
 * When he uses electrons and one slit then the result is a vertical line, while with two slits the result is a set of vertical lines. The Dr. expected what the result was equal that with the balls.

**** 6. What explanation does Dr. Quantum give? ** ** It was very confus__ed__ ING for __by__ me. When he introduces an observer the electrons did with the balls. Dr. Quantum said that the behavior of the electrons depend **** S on **** __of__ an observer. He concluded with the questions: What is matter? Particles or waves? **
