The dual character of matter particles in motion was postulated by De Broglie.
Louis de Broglie proposed the idea that particles like electrons could behave not only as particles but also as waves, a concept known as wave-particle duality
B. The square of the magnitude of its wave function
C. Its energy
D. Its momentum
Explanation
In quantum mechanics, the wave functionψ(x,t) describes the quantum state of a particle.
The probability density of finding the particle at a particular position in space is given by:
P(x)=∣ψ(x,t)∣^2
This means:
The square of the magnitude (or absolute value) of the wave function gives the probability per unit length (or volume) of finding the particle in that region.
This principle is known as the Born interpretation.
