I’m 30 never went to school but have a few questions please don’t judge if they sound displaced.first is about the use of arc light and laser pulses(together).second is about the post that brought me to this message board something about percieved light spectrum if the authors of that post are still around please reference to this post I guess these will be all (TOE) questions with only my own mechanical logic to back it.:smack:

**Moderator Action**

Please restrict your posts to a single topic each, otherwise they get confusing. Also, please do not cross post or repost. I removed your other post as it was basically just a copy of this one.

Use this thread to discuss arc light and laser pulses. If you have a question about another thread, please ask that question in that thread and state the question as clearly as possible.

Also, please use descriptive thread titles so that folks will have some idea what the topic is without reading the thread. I have modified the thread title on this one accordingly.

Thank you, and welcome to the SDMB.

What are you trying to ask about arc light and laser pulses? At first glance they have zero in common other than being light, that is electromagnetic radiation at wavelengths our eyes can see.

And what do you even mean by “arc light”? Are you referring to theater lights, or welding, or what?

What do you think these have in common or are different? How and why have you connected these two items? etc.

We can do a lot to answer clear questions. We can’t write a dissertation based on just two nouns. Help us help you.

I suspect this [Are the colours contiguous sections of the spectrum of visible light - Factual Questions - Straight Dope Message Board](http://boards.straightdope.com/sdmb/showthread.php?t=747957) is the thread about perceived spectrum. As the moderator requested, if you want to ask something related to that topic, please post it to that thread, not here.
