Let’s explore how the quantum theory of light explains the below experimental results of photoelectric effects. 1. The kinetic energy of the photoelectrons are independent of intensity but depend on frequency. 2. Below a minimum frequency called the threshold frequency, no photoelectric effect takes place, even if the light has very high
e. Quantum mechanics is the study of matter and its interactions with energy on the scale of atomic and subatomic particles. By contrast, classical physics explains matter and energy only on a scale familiar to human experience, including the behavior of astronomical bodies such as the moon. Classical physics is still used in much of modern

K m a x = h c λ − ϕ. We then let λ 1 and λ 2 be the wavelengths of the light emitted by the first and second sources, respectively, and we let K 1 and K 2 be the maximum kinetic energies of the corresponding photoelectrons. Therefore, K 1 = h c λ 1 − ϕ. K 2 = h c λ 2 − ϕ. where λ 2 = 0.5 λ 1. Therefore, K 2 − 2 k 1 = ϕ.

What Is The Quantum Theory Of Light
K m a x = h c λ − ϕ. We then let λ 1 and λ 2 be the wavelengths of the light emitted by the first and second sources, respectively, and we let K 1 and K 2 be the maximum kinetic energies of the corresponding photoelectrons.

Quantum optics is a branch of atomic, molecular, and optical physics dealing with how individual quanta of light, known as photons, interact with atoms and molecules.It includes the study of the particle-like properties of photons. Photons have been used to test many of the counter-intuitive predictions of quantum mechanics, such as entanglement and teleportation, and are a useful resource for

The earlier chapters describe the quantum mechanics of various optical processes, leading from the classical representation of the electromagnetic field to the quantum theory of light. The later chapters develop the theoretical descriptions of some of the key experiments in quantum optics. Over half of the material in this third edition is new.
