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 have not heard before

= = 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" ([]) "//vb// **slits**, **slitting**, **slit** //(tr)//
 * 1.** to make a straight long incision in; split open**2.** to cut into strips lengthwise**3.** to sever//n//**1.** a long narrow cut**2.** a long narrow opening" ([])

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

particles, waves, physics, slit, double.

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

Please click on the following link to watch the video and answer: []

Yes, the words that appear are: particles, waves, slit, double.
 * 1. Are there any of the words you mentioned in the previous question in the video?

2. What's the experiment about? Describe it.** This experiment is to tell the difference between how small particles act like marbles, waves and other infinitesimal as electrons passing through one or two slits.

Dr. Quantum to notice whether or not difference, had to see what happened to each particle, the marbles and waves as the electrons passing through one or two cracks. A total of six steps. Dr Quantum studied the outcome of the marbles through one and two slots, of the waves through one and two slots and too with the electrons.
 * a.What does he need to do the experiment?
 * b.How many steps does it have?
 * c.What happens in each step?

As this in the previous question there are three cases:
 * In the case of the marbles are experimenting with a slit and behind is a wall, in the wall reflects the line of marbles that pierced the slit and in the case of two slits are two lines on the wall. This is the case that we all expect.
 * In the case of waves are experimenting with a slit and behind it there is a wall, the wall reflects the bright line intensity as the wave propagates, similar to that of the marbles and in the case of two cracks start changes for an interference pattern of several bands.
 * Finally, in the case of electrons are experimenting with a slit behind it there is a wall, the wall reflects a line exactly equal that the marbles but in the case of two slits occurs an interference patter as with the waves, that is, do not reflects equal that the marbles.

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

Teacher, I had not seen either the questions and explain everything in the previous. Sorry :( ** No problem...  The waves reach the crack pass through it and spread to the wall, showing a line on the wall resulting from the spread. While that when the two slits are placed something different happens, as across the wall forms an interference pattern is not as marbles.
 * 3. What happens with balls and one slit? And with two slits?
 * 4. What about waves?

5. What happens with electrons 6. What explanation does Dr. Quantum give?**
