Physical Optics University physics, physical optics usually takes the wave nature of light as the main research object, and studies the propagation, interference, diffraction, polarization properties of light and the information processing of light from the two perspectives of electromagnetic wave theory and Fourier analysis.
Edited at 2023-12-29 20:16:47One Hundred Years of Solitude is the masterpiece of Gabriel Garcia Marquez. Reading this book begins with making sense of the characters' relationships, which are centered on the Buendía family and tells the story of the family's prosperity and decline, internal relationships and political struggles, self-mixing and rebirth over the course of a hundred years.

Project management is the process of applying specialized knowledge, skills, tools, and methods to project activities so that the project can achieve or exceed the set needs and expectations within the constraints of limited resources. This diagram provides a comprehensive overview of the 8 components of the project management process and can be used as a generic template for direct application.

nisini1=nrsinr
Visible light range
400-760nm
put one's oar in
double slit interference
δ=xd/D
thin film interference
δ=2necosr (r is the incident angle or refraction angle at which light is refracted in the medium)
Cutting edge interference
same as film
Additional consideration is given to the slope θ
△e=λ/2n
Bright pattern spacing L=△e/θ
Newton's rings
same as film
Consider additional arcs
Michelson's intervention
δ=2d
multi-beam interference
δ=dsinθ
Bright pattern: δ=kλ
Dark pattern: δ=kλ/N
Bright patterns cover dark patterns
Pay extra attention to half-wave loss
diffraction
single slit diffraction
half band method

Marius' law
Change in light intensity after passing through the polarizer (cosα)^2
Brewster's Law
When incident at Brewster's angle i, the reflected light is completely polarized.
