The quantum theory of light explains that light is made up of particles called photons. In the photoelectric effect, photons strike a metal surface, transferring their energy to electrons, which can then be emitted from the metal. This process demonstrates the particle-like behavior of light, as individual photons interact with electrons one at a time to cause emission.

What phenomenon cannot be explained on the basis of the wave theory of light?
The phenomenon of photoelectric effect cannot be explained on the basis of the wave theory of light. The wave theory predicts that the energy of a light wave is proportional to its intensity, whereas the photoelectric effect depends on the frequency of light.
What is the quatum theory?
Quantum theory is a branch of physics that describes the behavior of matter and energy on the smallest scales, such as atoms and subatomic particles. It introduces the idea of quantized values, where certain properties like energy or momentum can only exist in discrete, specific amounts. Quantum theory has led to groundbreaking discoveries and technologies like quantum computing and quantum teleportation.
What is quanta of energy?
A quantum of energy is the smallest possible discrete unit of energy. According to quantum theory, energy is quantized and can only exist in certain fixed amounts or packets called quanta. These quanta of energy can be transferred or exchanged during physical processes like light emission or absorption.
What is a photon amplitude?
Photon amplitude refers to the strength or magnitude of the electric field associated with a photon. It represents the maximum displacement of the electric field from its equilibrium position. In quantum theory, it is related to the probability amplitude of the photon being in a particular state.
What is de-Broglie theory?
De Broglie theory states that particles, such as electrons, can also exhibit wave-like properties. It relates a particle's momentum to its wavelength, forming the basis of wave-particle duality in quantum mechanics. This theory helped bridge the gap between classical physics and quantum mechanics.
What theory of light best explains the emission of electromagnetic radiation of an excited atom?
Quantum Mechanics
Why did Elmer Samuel Imes apply infrared spectroscopy to the quantum theory?
Elmer Samuel Imes applied infrared spectroscopy to the quantum theory to investigate the interactions of molecules with electromagnetic radiation and to provide experimental confirmation of quantum theory predictions. By studying the absorption and emission of infrared radiation by molecules, Imes was able to demonstrate the quantization of energy levels in molecules, supporting the principles of quantum mechanics.

What did Niels Bohr contribute to the atomic theory?
Niels Bohr developed the model of the atom that incorporated quantum theory, known as the Bohr model. This model proposed that electrons orbit the nucleus in fixed energy levels or orbits, explaining the stability of atoms and their emission spectra. His work laid the foundation for modern atomic theory and quantum mechanics.

What is the mathematics of combining quantum theory with wave motion of atomic particles?
Quantum theory describes the behavior of atomic particles in terms of probability waves. When combining quantum theory with wave motion, we use mathematical tools such as Schrödinger's equation to describe the wave function of a quantum system. This helps us understand phenomena like wave-particle duality and interference patterns in quantum mechanics.
What was The quantum theory of energy levels within atoms was aided by?
The quantum theory of energy levels within atoms was aided by the emission spectrum. When excited with light, different elements emitted photons of different frequencies. The frequencies were different because the energy difference from excited to low energy state was different depending on the element.
Who founded the quantum theory?
The original founder of quantum theory was Max Plank. The basic theory has been improved upon many times but there hasn't been a 'Modern Quantum Theory' that replaces the old.
