question about diffraction

Postby Nan_Guan_1L » Sun Nov 01, 2020 6:07 pm

Hi guys, I have a question regarding diffraction. I understand that as Dr. Lavelle puts it, if light acts as particles, there would be two patterns shown at the spot of the openings, but instead we get this diffraction pattern. I just don't understand why this diffraction pattern shown in the diagram necessarily means that light has wave-like properties. can someone please explain? thank you!

Hey, so as I understand it, there’s portions of the receiving wall which do not make contact with the electrons and it’s due to the constructive and destructive waves caused by the electrons, which is a wavelike property. Also, the electrons bend as they go through the edge of the wall, meaning it’s acting like a wave.

They have wavelike properties because they do not go into a straight line where the openings are, which is how particles act. Therefore, they must have some movement, and where they end up is unknown because of these waves.

The electrons must bend in order to go through the slits in this experiment because they cannot go straight through, as particles would. This means they must have wavelike properties as well as particle-like properties.

If the electrons were solely acting as particles, they would pass through the two slits in the board and make clear lines, but since they act like waves we see the pattern in the picture where that are points of overlapping waves.
