Einstein proposed that electrons on the surface of a metal gradually absorb energy from photons until they have enough energy to leave the surface?
There's nothing gradual about it. One photon sails by one electron. If it has the
correct amount of energy to boost the electron into the next higher energy
level, then the electron jumps to the next higher energy level. If it's not exactly
the right amount, then the photon just continues on its way.
Einstein's 'proposal' was backed by enough solid math and Physics, and did a
good enough job of explaining mysterious things that were observed in the lab
since 18 years earlier, that it won him the Nobel Prize in 1921.
That was 16 years after he proposed it. It took that long, because in order to
accept it, scientists had to start thinking of light as a stream of particles, like
little ping-pong balls, and that didn't go down easily.

What is a simple definition of Einstein's quantum theory of light?
Einstein's quantum theory of light, proposed in 1905, describes light as consisting of particles called photons that carry energy and momentum. It explains various phenomena such as the photoelectric effect, where light can eject electrons from a material, and the quantization of light energy into discrete packets.
Which subatomic particle of the atom in a molecule interacts with photons?
Electrons are the subatomic particles in an atom that interact with photons. When photons interact with electrons, they can be absorbed, emitted, or scattered, leading to various chemical and physical processes in a molecule.
How do electrons gain in energy in photosystem 1?
they absorb photons from sunlight
How did Einstein used Plank' theory to explain the existence of threshold frequency?
Einstein used Planck's theory of quantization to explain the photoelectric effect by proposing that light is quantized into packets of energy called photons. These photons have energy proportional to their frequency, and when light with frequency below the threshold frequency interacts with a metal surface, no electrons are emitted. Above the threshold frequency, each photon can transfer enough energy to overcome the work function of the metal, causing electrons to be emitted.
What are the statements proposed by neils bohr?
Niels Bohr proposed the quantized electron orbits in the atom, known as the Bohr model. He also introduced the principle of complementarity, which suggests that particles can exhibit both wave-like and particle-like properties depending on the experimental setup. Additionally, he proposed the concept of quantum jumps, where electrons transition between energy levels by emitting or absorbing photons.
Which scientist applied the concept of a quantum to explain the photoelectric effect?
Albert Einstein applied the concept of a quantum to explain the photoelectric effect in his 1905 paper. He proposed that light consists of discrete packets of energy called photons, which interact with electrons in materials to release them from the surface.
What was Albert Einstein's contribution to our understanding of the photoelectric?
he described light as little packets called photons
What characteristic of light did Einstein employ to explain the photo electric effect?
Einstein employed the particle-like nature of light, known as photons, to explain the photoelectric effect. He proposed that light is made up of discrete packets of energy (photons) that can transfer their energy to electrons in a material, causing them to be emitted. This idea helped to explain why the photoelectric effect occurred instantaneously at certain frequencies of light, as the energy of individual photons is proportional to their frequency.
What is Einstein photoelectric effect?
Einstein's photoelectric effect work found that the incident light involved in the photoelectric effect was made of individual quanta (photons) that interacted with the metal's electrons like discrete particles, not waves.
What did Albert Einstein call the quanta of light energy?
Albert Einstein called the quanta of light energy "photons."
Who proposed that light are particle?
Albert Einstein proposed that light can behave like particles in certain experiments, which led to the development of the concept of photons. This idea was instrumental in the field of quantum mechanics and revolutionized our understanding of the nature of light.
Which idea did Einstein first purpose to explain the photoelectric effect and the result of double-slit experiments?
Einstein first proposed the idea of photons as discrete packets of light energy to explain the photoelectric effect. According to his hypothesis, light is composed of individual particles called photons that transfer their energy to electrons upon striking a material surface. Additionally, Einstein's explanation of the double-slit experiments involved the concept of wave-particle duality, stating that light exhibits both wave-like and particle-like properties.
How the albert Einstein explain the photoelectric effect?
Apex Light is made of photons.
How did Albert Einstein explain photoelectric effect?
Apex Light is made of photons.
Who discovered light photons?
The concept of photons as particles of light was proposed by Albert Einstein in 1905 based on his explanation of the photoelectric effect. It was later confirmed through experiments by Arthur Compton in 1923, providing further evidence for the particle-like behavior of light.
What is a simple definition of Einstein's quantum theory of light?
Einstein's quantum theory of light, proposed in 1905, describes light as consisting of particles called photons that carry energy and momentum. It explains various phenomena such as the photoelectric effect, where light can eject electrons from a material, and the quantization of light energy into discrete packets.
Do photons conduct electricity?
No. Electricity is the movement of electrons, and photons have no electrons to move. Photons are the gauge particles for the electromagnetic force, but that's a different concept.
