O volume density​

Answer 1

Answer:

probability density

................

Answer 2

The square of the magnitude of the wave function is called probability density (Option-B).

• The probability amplitude with a complex value, which (in an isolated quantum system) tells about the quantum state of a particle is the wave function.
• Its square gives the probability density of a particle.
• Wave function's denotation is - "Ψ".
• And, the probability of finding the position of a particle at a particular instant of time is called the probability density.
• Its mathematical expression is-

      Probability density = [Ψ(x)]²

• here, x is the position of the particle at a particular instant of time t.
