Question

a.What does energy quantization mean? How is that different from classical physics?

b.Explain what is meant by wave-particle duality.

c.Estimate the uncertainty in your position when running across the quad.

d.Describe a particle-in-a-box.

Answer 1

a) The quantization of energy refers to the absorption or emission of energy in discreet packets, or quanta. As the intensity of electromagnetic energy increases or decreases, it steps up or down from one quantized level to another, rather than follow a smooth and continuous curve. The quantization of energy, also known as "quantum theory," describes how energy can only be lost or gained in multiples of a smallest possible unit of energy, which is referred to as a "quantum."

b) de Broglie in 1924 proposed that matter, just like radiation, should also exhibit dual behaviour i.e both particle and wavelike properties. This means that just as the photon has momentum as well as wavelength, electrons shold also have momentum as well as wavelength.
