Answer:
Explanation:
In the early 1800s (1801 to 1805, depending on the source), Thomas Young conducted his experiment. He allowed light to pass through a slit in a barrier, so it expanded out in wavefronts from that slit as a light source (under Huygens' Principle). In turn, that light passed through the pair of slits in another barrier (carefully placed the right distance from the original slit). Each slit, in turn, diffracted the light as if they were also individual sources of light. The light impacted an observation screen. This is shown to the right.
When a single slit was open, it impacted the observation screen with greater intensity at the center. It then faded as you moved away from the center. There are two possible results of this experiment:
Particle interpretation: If light exists as particles, the intensity of both slits will be the sum of the power from the individual slits.
Wave interpretation: If light exists as waves, the light waves will have interference under the principle of superposition, creating bands of light (constructive interference) and dark (destructive interference).
