Optical Properties of Materials presentation

[skyboarder2]

Hi everyone,

I'm trying to gather some ideas of subjects for an oral presentation in my Optical Properties of Materials class: I'd love to find something pleasant or at least nice to develop (like I heard "how a cameleon changes color?"^^), not too theoretical if possible... And with some websites/paper to prepare it...
Do you have some ideas which could help me? Thanks you a lot

That's a bit too much "not too theoretical"... But thank you though, if you think about anything else... Thanks a lot

How about discussing how a liquid crystal display works?

Typing "how LCD works" into google bring up everything from pics to video to very theoretical articles.

If you want to go further try typing in

nematic crystals

go well

Hello Skyboarder,

Thank you for reaching out for ideas for your presentation in your Optical Properties of Materials class. There are many interesting and engaging topics you could explore in this field. Here are a few suggestions to get you started:

1. The science behind color-changing materials: You could delve into the different mechanisms that allow certain materials to change color, such as structural coloration, chemical reactions, or thermal changes. You could also discuss the potential applications of these materials, such as in camouflage or smart fabrics.

2. Optical illusions and their explanations: This topic could explore how our brains perceive visual information and how certain materials or designs can create illusions that deceive our eyes. You could also discuss the role of optical illusions in art and design.

3. The use of optical properties in technology: This could cover a wide range of topics, from the use of optical fibers in communication to the development of solar cells using photovoltaic materials. You could also discuss the future potential of these technologies and their impact on society.

4. The role of optical properties in nature: This could include exploring how animals use optical properties for survival, such as how certain insects use iridescence for mating or how polar bears' fur traps light for insulation. You could also discuss how humans have drawn inspiration from nature to develop new materials with unique optical properties.

I hope these ideas help you in your search for a presentation topic. Remember to choose something that interests you and that you feel confident presenting. Best of luck with your presentation!
