Study Notes
Christian Huygens' Proposals
- In 1678, Christian Huygens proposed that light is a wave, and he was the first to suggest that light waves are propagated in a medium called the ether.
Interference of Light
- Interference of light is defined as the superposition of two or more light waves, resulting in a new wave pattern.
Types of Interference
-
Constructive Interference
- The result of constructive interference is a brighter region, where the amplitude of the light wave is increased.
- Occurs when the crests of the light waves align.
-
Destructive Interference
- The result of destructive interference is a darker region, where the amplitude of the light wave is decreased.
- Occurs when the troughs of the light waves align.
Huygens' Assumptions
- Christian Huygens assumed that light waves are similar to water waves, requiring a medium (the ether) to propagate.
