Introduction
Determination of the direction in which light travels might be a simple experiment, but quite significant in realizing essential theories and principles behind light travel. The physics of light is a cornerstone to an advanced physics, and other optical areas. The behavior of light is correspondent any behaviors exhibited by a particle or wave (Avison 35). Light is a particular kind of wave that behaves in a given manner. Below is the experimental procedure that shows how the path of light can be determined.
Materials
This experiment will require simple materials, which include:
Three pieces of simple index cards
Assortment of sticky tack or modeling clay for mounting the index cards
A torch or a flashlight
Puncher for making holes on the card indexes
A piece of a long ruler
Reference material for the experiment
Procedure
The ruler will be placed on the each index card in to connect opposite corners of these cards
The hole puncher will be used to make holes at the intersection of the two lines, and in the center of the index cards
The piece of modeling clay shall be used to create a stand for the three cards. The cards must be held in a vertical direction, and must be positioned at equal distance from one another.
Finally, the flashlight shall be placed at one end of the card, after turning off the light in the room. This shall be followed by observing the holes from the opposite end to determine the location of the flashlight. The boxes could be misplaced in order to determine whether one can observe the flashlight at the rare end.
Make observation in two scenarios and record the findings
