Heisenberg Uncertainty Principle

Presented by Chemistnotes.com

Heisenberg Uncertainty principle was proposed by a German physicist, Werner Heisenberg in 1927. The principle states that it is impossible to measure both the velocity and position of a particle accurately at the same time.

Position and momentum of an electron cannot be determined simultaneously with absolute accuracy.”

The particle with a well-defined wavelength while moving has precise velocity, but the position of particle becomes uncertain. H ence, It is very tough to measure both quantities accurately at the same time.

The more accuracy we calculate in the particle’s position, the less the precision will be in its velocity, and vice-versa. Arrow

Heisenberg’s Uncertainty principle tells us that it is impossible to know both the position and velocity exactly at the same time.
