Concept explainers
Interpretation:
The reason due to which it is impossible to know precisely the velocity and position of an electron at the same time needs to be explained.
Concept introduction:
Heisenberg’s uncertainty principle states that it is not possible to measure the momentum (velocity and position) of a minute particle moving with the

Answer to Problem 75A
The photon which is required to measure electron velocity or position of electron it changes both position and velocity of electron.
Explanation of Solution
Electrons can be seen only with high beam light. The photon which is required to measure electron velocity or position of electron changes both position and velocity of electron.
So it is impossible to measure both position and velocity simultaneously.
It is not possible to measure both position and velocity simultaneously.
