Apologies for answering so late, completely forgot about this thread. It went really well, thanks a lot for your help, the questions I got at the end were in fact quite interesting and made me glad I chose that subject, despite not knowing much about structural coloration before that. Funnily...
Sorry for the confusion, I was asking why it was specifically for λ=500nm, I understand how it achieves a zero reflectance and why that only applies for a certain wavelength, but I didn't know it was for λ=500nm because of the thickness of the layer. Many thanks.
To remove the reflection on the glasses, the additional layer creates a new reflection of the light in order for the two waves reflected to interfere destructively when having a phase difference of an odd multiple of π. So using the distance traveled by the two waves, we get, at normal...
Hi! I'm in my final year of high school and I need to present to a jury a 5 minute presentation on a physics question. I'm looking for a topic that would combine physics and everyday life , similar to explaining ball movement in a given sport through aerodynamics and movement trajectory. My...
