Which of the following pairs of concepts constitutes complementary variables as expressess by the Heinsberg uncertainty principle?
Answer Details
The Heisenberg uncertainty principle states that it is impossible to precisely determine both the position and momentum of a particle at the same time. Complementary variables are pairs of physical quantities that are related by the uncertainty principle.
Out of the options given, the pair that constitutes complementary variables is "position and momentum." This means that the more accurately you measure the position of a particle, the less precisely you can determine its momentum, and vice versa.
To give a simple example, imagine trying to determine the position and momentum of a ball. If you know the position of the ball very precisely, you would have to give up some information about its momentum, and if you know its momentum very precisely, you would have to give up some information about its position. This is a fundamental property of the universe that arises from the wave-like nature of particles at the quantum level.
