What three experimental facts about the photoelectric effect could only be explained by atoms idea of atoms absorbing photons a certain energy?
- Threshold frequency: The observation that electrons are only emitted when the incident light exceeds a certain frequency, regardless of intensity, supports the idea of atoms absorbing photons of specific energies to release electrons.
- Stopping potential: The linear relationship between stopping potential and frequency of incident light suggests that electrons gain a fixed amount of energy from absorbing individual photons with discrete energies.
- Photoelectric current: The instantaneous emission of electrons upon light exposure and the immediate halt of current when light is turned off indicates the discrete nature of photon absorption by atoms, supporting the quantized energy transfer.

What 3 experimental facts about the photoelectric effect could only be explained by the idea of atoms absorbing photons of lights of a certain energy?
The existence of a threshold frequency below which no electrons were emitted. The direct proportionality between the frequency of incident light and the kinetic energy of emitted electrons. The instantaneous emission of electrons once the threshold frequency was surpassed, rather than a delayed response as would be expected in a classical wave model.
Why can't the wave model cannot explain the photoelectric effect?
The wave model cannot explain the photoelectric effect because it assumes that energy is transferred continuously, while the photoelectric effect shows that electrons are emitted instantaneously when light of a certain frequency hits a material. This is better explained by the particle nature of light, as described by the photon theory.
What observations or experiments do not show light behaving as a classical wave?
Certain experiments such as the photoelectric effect and the Compton effect cannot be explained by classical wave behavior. The quantized nature of light revealed by these experiments led to the development of the quantum theory of light.
Which phenomenon can only be explained by assuming that light is quantized?
The photoelectric effect is a phenomenon that can only be explained by assuming that light is quantized. In this effect, electrons are ejected from a material when it is exposed to light of a certain frequency. The energy of the ejected electrons is dependent on the frequency of the light, supporting the idea that light is made up of discrete packets of energy called photons.
Ware did albert Einstein came up with the photoelectric effect?
Albert Einstein developed the theory of the photoelectric effect while working as a patent examiner in Bern, Switzerland in 1905. He proposed that light could be understood as consisting of particles called photons that interact with matter. This theory helped to explain certain behaviors of light that could not be explained by classical physics.

How is light absorbed and made into electricity?
light is absorbed by special cells known as photoelectric cells...... these cells are made uf certain materials that release electrons upon absorbing energy in the form of light...

Is there any importance in photoelectric effect?
One of the most revolutionary concepts in physics is the photoelectric effect. The photoelectric effect occurs when radiant energy is impinged on various metals and electrons are ejected from the metal surface. The ejected photoelectrons have a certain kinetic energy which can be measured by the produced voltage. Photoelectric current cannot be explained by the wave theory as diffraction and interference can, however. The photoelectric effect is important because it revealed some of the limitations of the classical wave theory and it gave closer insight into the nature of light- namely the quantization as photons.
What is the emission of electrons from a metals surface when light of a certain frequency shines on it?
photoelectric effect
Are photoelectric smoke alarms worth the cost?
Photoelectric smoke alarms will help you in the case of certain smoke being in the air. They can be found online at http://www.firesafetycouncil.com/pdf/review_on_best_sensor_type_for_kitchens.pdf.
What is the phenomenon in which electrons are emitted from a metals surface when light of a certain frequency shines on it?
Photoelectric phenomenon
What happens to electrons in the photoelectric effect?
When you shine a certain level of light wavelength on metal, you can knock electrons off the atoms of the metal. This phenomenon was explained by Albert Einstein in 1905, for which he received a Nobel Prize in 1921.
What was albert einsteins's contribution to our understanding of the photoelectric effect?
He wrote a paper that described the photoelectric effect. The paper contained equations used to explain why certain wavelengths of light cause the p-e effect but others do not and the energy changes in the electrons during the p-e effect.
