Definition
| A transverse wave composed of an oscillating electric field and a magnetic field that oscillates perpendicular to the electric field |
|
|
Term
| Define: The Law of Reflection |
|
Definition
| The Law of Reflection – The angle of reflection equals the angle of incidence |

|
Term
| Be able to describe light according to the currently accepted theory. Be very detailed. |
|
Definition
| Light is made up of individual packets. Each packet is made up of two perpendicular transverse waves: one that consists of an oscillating electrical field, and one that is made up of an oscillating magnetic field. |
