SimReal: Physics - Light - Reflection UiA Logo


[SimReal] [Library]


In the picture to the left you see two points A and B and a horizontal line.
Three questions that can be answered by the same strategy:

1:
Where should we place a point C on the horizontal line to construct the shortest line ACB?

2:
Where should we place a point C on the horizontal line to run fastest along the line ACB running with constant speed?

3:
Sending light from A, at what point C on the horizontal will the light be reflecting to the point B?



Use this simulation and/or go to Exercise to try to find the answers to these three questions.
