Study Notes
What is a Mirror?
- A mirror is a reflective surface that shows a clear image
- Mirrors are super smooth surfaces, unlike regular surfaces like dining room tables which appear smooth on a large scale but have peaks and valleys when magnified
- The smoothness of a mirror allows light to bounce off it in predictable ways
Ray Tracing
- Ray tracing is a method of illustrating the path of light as a straight line coming from a source
- It helps to show how light moves in a particular situation
The Law of Reflection
- The law of reflection states that the angle light hits a surface (incident angle) is equal to the angle light bounces away from the surface (reflected angle)
- This law applies to all surfaces, including mirrors and irregular surfaces like dining room tables
- On irregular surfaces, light bounces off in many directions (diffuse reflection) due to peaks and valleys on the surface
How Mirrors Work
- A mirror's smooth surface allows parallel rays to follow the law of reflection and bounce off still parallel
- This results in the creation of an image
- When looking at a mirror, the image appears to be behind the mirror because light rays hit the body, bounce off the mirror, and then head back to the eyes
- Symmetrical light rays bounce off a mirror symmetrically, following the law of reflection
