Heisenberg's Uncertainty Principle tries to explain the potential duality of an electron behaving as either a particle or wave.
Heisenberg's Uncertainty Principle illustrates that an electron can behave as a particle or as a wave, but never both simultaneously.
Concept: The duality of an electron.2m
Concept: To illustrate this dual nature of an electron Heisenberg created his Uncertainty or Indeterminacy Principle4m
Example: An electron has an uncertainty in its position of 630 pm. What is the uncertainty in its velocity?5m
A student is examining a bacterium under the microscope. The E. coli bacterial cell has a mass of = 0.500 (where a femtogram,fg , is 10-15 g) and is swimming at a velocity of v = 9.00 um/s, with an uncertainty in the velocity of 8.00 %. E. coli bacterial cells are around 1 um (10-6m ) in length. The student is supposed to observe the bacterium and make a drawing. However, the student, having just learned about the Heisenberg uncertainty principle in physics class, complains that she cannot make the drawing. She claims that the uncertainty of the bacterium's position is greater than the microscope's viewing field, and the bacterium is thus impossible to locate.
What is the uncertainty of the position of the bacterium? Express your answer numerically in meters.
