Is there a time delay with the photoelectric effect?

Is there a time delay with the photoelectric effect?

There is no time lag between the incidence of photons and emission of photoelectrons in photoelectric effect. No. There is no time lag between the incidence of photons and emission of photoelectrons in photoelectric effect. This is one of the major drawbacks of wave theory.

What is the time lag between the incidence of photons and the injection of photoelectron?

Explanation: There is no time lag between the incidence of photons and emission of photoelectrons in photoelectric effect. The electron is emitted instantaneously with kinetic energy equal to the difference between the energy of incident photon and the threshold energy.

Is there a time lag between the incidence of radiation and the emission of electrons from a metal?

There is no time lag between the instant the photon of light falls on the metal surface and the instant a photoelectron is emitted from the metal surface. If wave nature of radiation is assumed, then it will take quite a long time (about an year) for electron to come out of the metal surface.

What occurs at the surface of a metal during the photoelectric effect?

The photoelectric effect is the observation that under certain conditions, light striking a metal surface can cause electrons to be ejected. As we shine light on the plates, going from low energy red to high energy blue, suddenly current begins to flow. …

Why does photoelectric emission occur without delay?

the surface, provided the frequency of the radiation exceeds the threshold frequency, and regardless of intensity. photoelectric emission occurs without delay. incoming wave regardless of how many waves arrive per second. So emission would occur but may be delayed.

What does the lack of a lag time imply about the nature of the electron in the metal?

The absence of a lag time means that these one-on-one interactions occur instantaneously. This interaction time cannot be increased by lowering the light intensity. The light intensity corresponds to the number of photons arriving at the metal surface per unit time.

What is the time lag between the incidence of photons and the ejection of photoelectrons a greater than 10 5 SB between 10 5’s and 10 9 SC less than 10 9 SD 1 second?

Practically, there is no time lag (< 10-9 s) between the incident photon and emission of an electron. 4.

What happens to the photoelectric current when the distance between a point source of light and photocell is doubled?

The emission of electrons per second will be doubled.

What is photoelectric effect does the effect support particle nature or wave nature of light?

The photoelectric effect supports a particle theory of light in that it behaves like an elastic collision (one that conserves mechanical energy) between two particles, the photon of light and the electron of the metal.

How photoelectric effect explain particle nature of light?

Photoelectric Effect and the Particle Nature 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.
