Quantum model/Electron config Quiz Review

Why wave nature of matter is not apparent to our daily observations?

• bodies travel with small velocities

• wavelength of the waves associated with the pretty heavy mass is very large

• bodies travel with large velocities

• wavelength of the waves associated with the pretty heavy mass is very small

The equation of motion of matter waves was derived by

• Heisenberg

• Bohr

• De Broglie

• Schrodinger

What do the different parts of the de Broglie equation (λ = h / mv) equal?

• h = Planck's constant, m = meters, v = frequency

• h = Planck's constant, m = meters, v = velocity

• h = Planck's constant, m = mass, v = frequency

• h = Planck's constant, m = mass, v = velocity
