@shirinkhan12 I see you sincerely are trying to convey certain fundamental concepts of QM. It's a bit hard to parse because it clearly wasn't written by someone for whom english is a native language.
I'll give you an A for effort here.
But you should be advised that I have a bot that scans the blockchain looking for content based on a "conceptual similarity index".
This looks an awful lot like you took the english wikipedia article on the double slit experiment, tried to translate it to your native language and then tried to explain certain parts verbatim. Possibly just translating in and out directly.
The conceptual flow is certainly a 1:1 for the original wikipedia article...

I'll give you the benefit if the doubt if you can explain the relationship between the math terms you inserted, which involve delta r over delta t.
If you're sincerely interested in the topic of quantum mechanics and not just trying to slip some content past @cheetah and @anyx please feel free to join us in discussing some exciting new developments in this field.
