Passage 2
Newton's surprising success at developing the laws of motion, as well as the development and refinement of other physical laws, led to the idea of scientific determinism. The first expression of this principle was in the beginning of the nineteenth century by Laplace, a French scientist. Laplace argued that if one knew the position and velocity of all the particles in the universe at a given time, the laws of physics would be able to predict the future state ofthe universe.
Scientific determinism held sway over a great many scientists until the early twentieth century, when the quantum mechanics revolution occurred. Quantum mechanics introduced the world to the idea of the uncertainty principle, which stated that it was impossible to accurately measure both the position and the velocity of a particle at one time. Because Laplace's omniscience could never occur, even in theory, the principle of scientific determinism was thrown into doubt. However, quantum mechanics does allow for a reduced form of scientific determinism. Even though physicists are unable to know precisely where a particle is and what its velocity is, they can determine certain probabilities about its position and velocity. These probabilities are called wave functions. By use of a formula known as the Schrodinger equation, a scientist with the wave function of a particle at a given time can calculate the particle's future wave function. These calculations can give the particle's position or velocity, but not both. Thus, the physicist is in possession of exactly half ofthe information needed to satisfy Laplace's view ofdeterminism. Unfortunately, under modern physics theories, that is far as any researcher can go in predicting the future.
Q. According to the passage, wave functions:
  • a)
    allow scientists to determine the position and velocity of a particle
  • b)
    are determined by the Schrodinger equation
  • c)
    provide a range of possible locations and velocities for a particle
  • d)
    allow a scientist to calculate the future state of the universe
Correct answer is option 'C'. Can you explain this answer?

The relevant part of the passage is here: "Even though physicists are unable to know precisely where a particle is and what its velocity is, they can determine certain probabilities about its position and velocity. These probabilities are called wave functions." Since wave functions are probabilities, they present a range of possibilities, as choice C states.
Choice A is contradicted by the passage.
Choice B is incorrect based on the information in the passage.
Choice D is wrong because wave functions only allow scientists to figure out a probability, not the future state.

Wave functions:
Wave functions provide a range of possible locations and velocities for a particle.
- Wave functions do not allow scientists to determine the position and velocity of a particle with certainty.
- They are determined by the Schrodinger equation, which is a fundamental equation in quantum mechanics.
- Wave functions represent the probabilities of finding a particle in different positions and with different velocities.
- By using the Schrodinger equation, scientists can calculate the future wave function of a particle based on its current state.
- These calculations give a range of possible outcomes for the particle's position and velocity, rather than exact values.
Therefore, wave functions in quantum mechanics do not provide precise information about the position and velocity of a particle, but rather offer a probabilistic description of its potential states.
