Which phenomenon Cannot be explained by wave nature of light?
In the photoelectric effect, we have a source of light which makes an incident on a metal surface. As the light falls on the metal, electrons are ejected from the surface of the metal. This phenomena cannot be explained by the wave nature of light.
Can the wave model of light explain what you saw happen in the photoelectric effect simulation?
Physicists expected that the electron would be ejected when a threshold of energy was absorbed. So since the entire surface is receiving energy at the exact same rate, the electrons should receive that threshold energy at the same time. Wave theory alone does not explain the photo-electric the affect.
Which phenomenon can be explained by wave nature of light?
Photoelectric effect demonstrates the wave nature of light.
Which theory can be explained on the basis of photoelectric effect?
The photoelectric effect can be explained on the basis of the Quantum theory of light.
What is the phenomena that can be explained only by the particle model of light?
A key experiment that was explained by Einstein using light’s particle nature was called the photoelectric effect. The photoelectric effect is a phenomenon that occurs when light shined onto a metal surface causes the ejection of electrons from that metal.
Which phenomenon can be explained based on the wave nature of light Mcq?
Phenomenon explaining the wave nature of light is/are: Interference.
Which phenomenon of light proves conclusively the wave nature of light?
Thus, the transverse nature of light was confirmed by the phenomenon of the polarization of light.
Can wave theory explain polarization?
The wave theory of light can perfectly explain some effects of light such as diffraction, polarization, and interference. However, it also fails to prove some theories and observations such as the photoelectric effect and the Compton Effect.
How photoelectric effect is explained on the basis of quantum and classical theory?
Photoelectric effect can only be explained by the quantum concept of radiation. 1) The photocurrent is proportional to the intensity of incident radiation. 2) The magnitude of stopping potential and hence the maximum kinetic energy of emitted photoelectrons is proportional to the frequency of emitted radiation.
Can the photoelectric effect be explained by considering light as a wave?
Introduction History of the Photoelectric Effect Principle Formula Laws Governing the Photoelectric Effect Experimental Study of the Photoelectric Effect Einstien’s Photoelectric Equation Graphs Applications Solved Problems (Numericals) The photoelectric effect cannot be explained by considering light as a wave.
What phenomena can only be explained when light is treated as waves?
The phenomena such as interference, diffraction, and polarization can only be explained when light is treated as a wave whereas the phenomena such as the photoelectric effect, line spectra, and the production and scattering of x rays demonstrate the particle nature of light.
What is the kinetic energy of photoelectron emitted from a photon?
For λ = wavelength of the incident photon, then If λ < λ Th, then the photoelectric effect will take place and ejected electron will possess kinetic energy. If λ = λ Th, then just photoelectric effect will take place and kinetic energy of ejected photoelectron will be zero. If λ > λ Th, there will be no photoelectric effect.
What is threshold frequency in photoelectric effect?
The photoelectric effect is defined as a phenomenon in which the emission of electrons occurs when a beam of light strikes a metal or a cathode surface. For the emission of electrons to take place, the frequency of incident light is required to be greater than a certain minimum value. This value is known as the threshold frequency.
