Quantum theory of light explains the behavior of light in terms of particles called photons.
Who proposed the quantum theory of light?
Albert Einstein proposed the quantum theory of light in 1905.
What is a photon?
A photon is a fundamental particle of light that carries energy and behaves both as a particle and a wave.
What is the photoelectric effect?
The photoelectric effect is the emission of electrons from a material when light of a certain frequency or higher is shone upon it.
What is light made of?
Light is made up of tiny particles called photons, which have no mass but carry energy.
How does the quantum theory of light explain the behavior of light?
The quantum theory of light explains that light can behave as both particles and waves, and its energy is quantized into discrete packets called photons.
What is the dual nature of light?
The dual nature of light refers to its ability to behave as both particles and waves.
What is the relationship between energy and frequency of light?
The energy of a photon of light is directly proportional to its frequency.
What experiment provided evidence for the particle nature of light?
The photoelectric effect experiment provided evidence for the particle nature of light.
What experiment demonstrated the wave nature of light?
The double-slit experiment demonstrated the wave nature of light.
What is the speed of light in a vacuum?
The speed of light in a vacuum is approximately 299,792,458 meters per second.
What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation, including visible light.
What is the wave-particle duality principle in quantum theory?
The wave-particle duality principle states that all particles, including photons of light, can exhibit both wave-like and particle-like behavior.
What is the Planck's constant?
Planck's constant is a fundamental constant that relates the energy of a photon to its frequency: E = hf, where E is energy, h is Planck's constant, and f is frequency.
What are some applications of quantum theory of light?
Quantum theory of light is applied in various fields including lasers, telecommunications, solar cells, and quantum computing.
