Question

1. choose the best answers.

the inability to describe the perfect position and motion at which an object moves is the __ and was proposed by __.
uncertainty principle; schrödinger
wave - particle duality of matter; heisenberg
wave - particle duality of matter; schrödinger
uncertainty principle; heisenberg

Explanation:

The uncertainty principle states that it is impossible to simultaneously know the exact position and momentum (motion - related quantity) of a particle. It was proposed by Werner Heisenberg. Wave - particle duality of matter is about particles having both wave - like and particle - like properties. Schrödinger is known for the Schrödinger equation which is related to the wave function of a quantum system.

Answer:

uncertainty principle; Heisenberg
