Why are Gaussian beams important?
Gaussian beams are important because they provide a mathematical model for describing the propagation of electromagnetic waves, particularly in laser technology. Their unique properties, such as diffraction-limited divergence and symmetric intensity distribution, make them ideal for various applications.
What does a prism do?
I'm curious about the function of a prism. I want to understand what happens when light passes through it and how it affects the light's properties.
