Question

the quantity which varies periodically in matter waves is____​

Answer 1

Answer:

The oscillating quantity in matter wave is probability-amplitude, a complex number . Suppose the electron is in state |ψ⟩. The wavefunction of finding the electron at any coordinate x is given by ⟨x|ψ⟩=Ae− i Et/ℏ⋅ e i p x/ℏ. Probability of finding the electron around x is given by P(x, x+ dx)=|ψ(x)|2dx=|⟨x|ψ⟩|2dx.

Answer 2

The quantity which varies periodically in matter waves is probability-amplitude.

Probability Amplitude:

• Probability Amplitude is the complex number that gives the relation between the waves
• It is used for prediction to find the energy discharge from the atom which is calculated by born probability
• It tells about the motion of one-dimension
• With the help of probability amplitude, we find the position space of the particles
• It found wave function in atoms and also tells about the density of electrons
