Click For Summary

Discussion Overview

The discussion centers around the distinction between holography and holograms, particularly in the context of an assignment on holography. Participants explore definitions, applications, and the relationship between the two concepts.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant seeks clarification on whether to include holograms in an assignment focused on holography.
  • Another participant emphasizes the importance of independent research before asking for help, suggesting that vague questions are less effective.
  • A participant provides a definition of holography as the process of making holograms and describes the two main types of holograms: reflection and transmission.
  • There is a suggestion that the term "holograph" may cause confusion, as it refers to a handwritten document, distinct from holography.
  • Some participants express frustration over the lack of effort shown in the initial inquiries and encourage the use of available resources for research.
  • A comparison is made stating that holography is to holograms what photography is to photos.
  • A participant confirms that including holograms in the assignment is acceptable since holography involves the creation of holograms.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to the assignment, with some advocating for a more focused study on holography while others suggest that discussing holograms is relevant.

Contextual Notes

Some participants express uncertainty about the depth of information available on holography, indicating a potential limitation in resources or understanding of the topic.

Please explain the difference between holography and holograms. I have to do an assignment on holography, but should I research holograms aswell.
Thanks

Your "research" and assignment should included you trying to find out for yourself first, and not simply hoping to get an outright answer on here. Try to find out what they are, and then, if you find something you do not understand, then ask specific questions on here. Do not ask vague, general questions without giving any indication that you've attempted them on your own.

This is my opening paragraph is it good. Is the information I have placed right please check. "Holography is the process of making or the technique of making holograms. It is an advanced type of photography, which allows the image to be seen in 3D. Holograms work by bouncing laser light off an object. There are two major types of holograms, reflection and transmission holograms. Reflection holograms work by reflecting a beam of laser off the surface of the hologram, but they are very expensive to make as they are in very high quality. The second one, transmission holograms make images by sending light through the holograms, these are cheap to make and are usually mass produced. E.g. the holograms in driving license. "
Thanks
 


Try a dictionary.

You describe holograms. If you are wondering what a holograph is, it is a document written in the author's own handwriting. Tryhttp://en.wikipedia.org/wiki/Holograph" . It took about two seconds to find that.

It opens with "Not to be confused with holography." So, the principle meaning of "holography" is the practice of making holograms. Your paper on "holograms and holography" is what you are describing in your paper. You might want to mention the confusion with "holograph", a must older word still in use in Law and history.

Oh NO really. But I can't find much information on holography. So I thought if I explain that holograhy is the process of making holograms, then explaining holograms was ok. Can you maybe post some websites I could use for holography. (OF course wikipedia). Thanks
 


It would be nice to know what you have looked at first because, once again, it will show that you've made an effort. I'm still not sure what exactly you are going to write on, and what you are having problems with.

So at the risk of spoon-feeding you the answer (which I truly hate to do), I will simply give you a popular fall-back website that has an entry on this. Please bookmark the hyperphysics website from now on and try and use that first.

We have so many resources available at our fingertips nowadays (you don't want to hear stories about the old days where we have to walk several blocks to get to a library, in the cold of winter, uphill and in barefeet, just to look up on a subject). There isn't much of an excuse anymore for someone to come in here completely blank cold on a topic. It is more effective (and a more effective use of this forum) when we tackle a specific issue or problem, rather than broad, vague topic.

Holography is to holograms what Photography is to photos.
 


Thanks guys. I just needed to know if holograms was ok in a holography subject. My assignment is on holography, but I thought it had to be exactly on it. SO I guess I can use holograms in this as well as holography is the process of making holograms.
