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.
What else can I help you with?
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.
Is there a phenomenon that does not support the wave nature of light?
Yes, the photoelectric effect is a phenomenon that does not support the wave nature of light. It demonstrates particle-like behavior of light as photons transfer their energy to electrons in a material, causing them to be emitted. This phenomenon cannot be explained using a wave model of light.
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.
What causes light to have different colors and how is this phenomenon explained by the principles of physics?
Light has different colors because of its varying wavelengths. The phenomenon is explained by the principles of physics through the concept of light being made up of different colors in the electromagnetic spectrum. Each color corresponds to a specific wavelength, and when light interacts with objects, certain wavelengths are absorbed or reflected, resulting in the perception of different colors. This is known as the principle of light absorption and reflection.
What does not support the wave nature of light?
The photoelectric effect does not support the wave nature of light. This phenomenon can only be explained by the particle nature of light, as described by Albert Einstein in his theory of photons.

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 did rutherfords model fail to explain why elements had?
Rutherford's model failed to explain why elements emit light at specific frequencies when heated. This phenomenon, known as atomic emission spectra, was later explained by Niels Bohr's model of the atom which introduced the concept of quantized energy levels in the atom.
What spectrum is evidence for quantized change?
The electromagnetic spectrum provides evidence for quantized changes in energy levels of atoms. This is seen in the emission or absorption of specific discrete frequencies of light, which is a result of electrons jumping between quantized energy levels within the atom. This phenomenon is described by quantum mechanics.
Is there a phenomenon that does not support the wave nature of light?
Yes, the photoelectric effect is a phenomenon that does not support the wave nature of light. It demonstrates particle-like behavior of light as photons transfer their energy to electrons in a material, causing them to be emitted. This phenomenon cannot be explained using a wave model of light.

Why does the photoelectric effect support the idea that light can behave as a particle?
The photoelectric effect is the emission of electrons when light shines on a material. This phenomenon supports the idea of light behaving as a particle (quantum) because it shows that light energy is quantized and can transfer a discrete amount of energy to electrons in the material, causing them to be emitted.
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.
Which property of light is not explained ny the wave model of light?
The wave model of light cannot fully explain the photoelectric effect. This phenomenon involves the emission of electrons from a material when it is exposed to light, and it requires the particle-like behavior of light to be understood.
What did Young's observation of an interference pattern for light show about the nature of light?
It shows that light behaves as a wave phenomenon. Interference cannot be explained using a particle theory. http://www.physicsclassroom.com/class/waves/Lesson-3/Interference-of-Waves
Which properties of light defines light as a wave?
It can be reflected, refracted and polarised. It also shows the phenomenon of interference. (Young's double slit experiment) The above are the properties of waves. Light shows these properties and thus, this defines light as a wave.
