7	Laws of Light

7.1 INTRODUCTION

Basic understanding of the reflection and refraction properties of light paved the way for many of the optical measuring devices in use today. When light strikes a surface, a portion of the incident ray is reflected from the surface. Depending on the surface characteristics, either specular reflection or diffuse reflection is observed. When light passes through an optically dense media, such as glass or water, the incident light ray bends as it enters the media. The characteristics of the material (air, glass, water, etc.) and the orientation of the ray determine the path of a reflected or refracted ray.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
