I needed a laser.

Hmm... I'm not to collage yet but from the problems you describe, I fell that if you offer them to opportunity to video chat with you at speculated times so they can ask questions, and work on problems "under your supervision" they might do better. I understand you have a personal life and this...

Thank you all, I talked to my science teacher, and he agreed with me that this is too hard, and because I was the one to bring it to his attention, I still got the extra credit. (that doesn't mean I won't try to make one still)

I don't have any way to see invisible light, is there something I can download on my phone. How could I build up electrons around the laser circuit? (what does eg mean) I thought a laser was a pinpointed light. Thanks for the help. (and actually reading my question)

The reason I'm going through all this is because my science teacher said he would give extra points to anyone who can make a laser. To get into Harvard you have to have a GPA of at least 4.04.

what do you "attenuated" The first light house was one of the 7 wonders, it used a fire for the light source. It was as tall as a 44 story building, so they would have had to magnify it some how. Can you explain how this works?

I don't know I was hoping one of you could tell me. So far So I can't do it? What about a light house, how do the make the lights so bright? If I could magnify the light in a similar way, I could buy a big magnifying glass. or Could I use a laser pointer, the emitter will be tiny.

I know but I want to do is with a flash light in a dark room.

Is it possible for me to make a flash light into a "laser" hot enough to burn through paper. Here is what I have: a light prism, 2 light splitters,(the can separate light so it goes 2 ways) 2 magnifying glasses, and a microscope.(I don't want to use it though) If there is any thing else you...

Thank you but I didn't really understand. Can you explain for a amateur to understand?

Thank you, are there solid and liquid forms for all gasses too for example is there a liquid form for carbon?

Thank you so much. So just to clarify you do get plasma by ionizing gas. Do you ionize something by super heating it? Thank you so much!

Theoretically you can travel back in time by moving faster than the speed of light, or the universal speed limit. Is there a minimum speed? 0. But with gravity you would be moving, so if you move against gravity relative to yourself you are moving. So if there was a place in the universe free of...

That black holes are black, not colorless.

I sort of new to the states of matter, so please use English (explain what all the big words mean). First of all what does ionizing even mean? second every type of matter of 4 states?
