    Grating
AI Thread Summary
A "Wood's Replica Grating" is a type of diffraction grating used to analyze the spectra of light sources, often constructed by students in physics labs. The discussion highlights the connection between the grating and the owner's father, who had a background in physics and a personal interest in optics and photography. The user expresses gratitude for the information received and acknowledges the relevance of the grating to their father's academic materials. There is a curiosity about the grating's origins and its specific applications in relation to the father's career as a missile systems analyst. Understanding the basics of the replica grating and its historical context is the primary goal of the inquiry.

I am not a physics student, but my father was.

I found a "Wood's Replica Grating" among his belongings after he died and have been scouring the internet trying to understand what this replica grating was used for. I think I am on the right track with optics, but I'd like to know more.

Can anyone help me so I can understand the basics of the replica grating?

Does anyone know when the "Wood's Replica Grating" was first created?

Thank you very much for your help.

Here is a brief bio of http://www.europa.com/~telscope/wood.txt" . I find other references to "Wood Gratings". This is a diffraction grating which is used to analize the spectra of light sources. I appears that some old phyiscs labs had students constructing Woods gratings. This is probably what you have.

Yes, I found online references to Wood's grating, but I wasn't able to understand its specific use, so I appreciate your reply.

And thanks for the link, I found the biography of Wood quite informative...and now realize the connection between his copy of Physical Optics textbook by Wood (my dad kept most of his college textbooks)...and the grating. It didn't make sense to me that he would have used this in his career as a missile systems analyst, but I knew he was interested in photography, telescopes and lenses of various sorts... I have been curious to know where the grating came from.

So, thank you very much for your prompt reply. I appreciate the information.

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
