# How Do Light Rays Travel from A to B via Refraction or Reflection?

• jamieXX96
In summary, the homework directions require tracing light rays from A to B via refraction or reflection and determining the equal angles. The provided solution includes the original diagrams with red lines indicating equal angles and dotted lines representing the normal. In the first picture, reflection is responsible for the light's path, while in the second, both reflection and refraction play a role.

## Homework Statement

The directions state that you "must trace the light rays that would travel from A to B via refraction or reflection. Show what angle must be equal to what. Why does light take the path you charted

## The Attempt at a Solution

I have provided the originals and then I traced the light rays, and then put in red the angles that were equal. The dotted lines are the "normal".

In the first picture the light takes the path that it does because of reflection. In the second it is because of reflection and refraction.

hi jamieXX96!

(except that your middle dotted line in the first diagram is obviously not the normal! )

## What is "Tracing Light Rays from A to B"?

"Tracing Light Rays from A to B" is a scientific process that involves following the path of light rays from a starting point (point A) to an ending point (point B). This can be done using various techniques and equipment, such as mirrors, lenses, and detectors.
