Why the photoelectric effect Cannot be explained by the wave theory of light?
Photoelectric effect cannot be explained on the basis of wave nature because experimentally we know that we need a particular energy called the work function of the metal surface. Unless this energy is provided, the electron won’t be ejected, irrespective of the time for which light is incident.
Why wave theory fails to explain the phenomenon of photoelectric emission What is Einstein’s photoelectric equation and how it explained the laws of photoelectric effect?
Photoelectric effect cannot be explained acoording to wave theory because of follwoing reasons: According to wave theory, after the light falls on a substance electrons are emitted after a small instant of time. However, in photoelectric effect, the electron emissions are immediate without a time delay.
Why wave nature of light could not explain black body radiation?
I was taught in class (or maybe I interpreted it this way) that if energy would be continuously radiated, then the intensity of radiation must increase on heating the black body and wavelength of light would stay same. But from experiment, wavelength changes. Hence it fails to explain it.
Which of the following property does not support wave theory of light?
Photoelectric effect cannot be explained on the basis of wave theory of light.
Which of the following can be explained on the basis of wave theory of light?
Answer: On the basis of the wave theory, the phenomenon of reflection, refraction, diffraction, interference, polarization and total internal reflection of light could be explained.
How does wave theory explain the nature of light?
Following wave theory, light can be seen as a form of energy in the electromagnetic spectrum. When looking into the light source, the eye can see the light coming directly. This light from the source is visible [A]. Light from the light source reflecting on the object [B] reaching the eye is also visible.
Why the wave model of light Cannot explain the energy emissions from a blackbody radiator but the particle model of light can?
Why can’t wave theory of Light explain the photoelectric effect?
a) Wave theory of light cannot explain the photoelectric effect because of the following reasons: i) Wave nature does not explain the instantaneous ejection of photoelectrons. ii) It does not explain to us the threshold frequency for a metal surface.
What is the difference between photoelectric effect and photoelectirc effect?
However, in photoelectric effect, the electron emissions are immediate without a time delay. 2. The energy of a wave increases with increase in intensity. However, in photoelectirc effect, increase in intensity has no effect on the energy of electrons emitted.
What is Einstein’s explanation of the photoelectric effect?
According to the Einstein explanation of the photoelectric effect is: The energy of photon = energy needed to remove an electron + kinetic energy of the emitted electron i.e. hν = W + E
What is the relationship between light intensity and energy of photoelectric current?
The photoelectric current is directly proportional to the light intensity. The kinetic energy of the photoelectrons is directly proportional to the light frequency. The stopping potential is directly proportional to the frequency and the process is instantaneous.
