Answer:
A) An interference pattern
Explanation:
the two slit experiment is key to understand the microscopic world. The wave-like properties of light were demonstrated by the famous experiment first performed by Thomas Young in the early nineteenth century. In original experiment, a point source of light illuminates two narrow adjacent slits in a screen, and the image of the light that passes through the slits is observed on a second screen.
Key Points
- waves can interfere, for light this will make a series of light and dark bands
- matter particles, such as electrons, also produce interference patterns due to their wave-like nature
- so with a high flux of either photons or electrons, the characteristic interference pattern is visible
