Photoelectric current and frequency
WebAboutTranscript. Let's explore how the graph of stopping potential vs frequency can be used to calculate the Planck's constant experimentally! From Einstein's photoelectric equation, this graph is a straight line with the slope being a universal constant. This slope has the value of h/e. In an effort to disprove Einstein, Robert Millikan ... WebJan 20, 2012 · 3.For a given metal of particular work function, increase in frequency of incident beam increases the intensity of the photoelectric current. 4.Above the threshold frequency, the maximum kinetic energy of the emitted photoelectron is independent of the intensity of the incident light but depends on the frequency of the incident light.
Photoelectric current and frequency
Did you know?
WebIn the case of the photoelectric effect, energy and frequency are independent of the intensity of the radiation; So, the intensity of the incident radiation affects how quickly the gold leaf falls, not the frequency ... Photoelectric Current The photoelectric current is the number of photoelectrons emitted per second; WebThe effect of changing incident frequency v can also be studied from the plot of photoelectric current Vs potential applied across CD, keeping the intensity of incident radiation same. From graph, we see that i max is same in all cases (for same intensity). From graph, as v increases, V c becomes more negative.

Webvariations in photoelectric current and intensity of light however, it is challengeable because in actual practice after a specific frequency photoelectric effect is not caused (or in other words photoelectric current is not produced) regardless of the …
WebApr 12, 2024 · Photoelectric effect is the emission of electrons when electromagnetic radiations having sufficient frequency incident on certain metal surfaces. We call the emitted electrons as photoelectrons and the current they constitute as photocurrent. WebJun 7, 2012 · It is also said that the frequency of the photons does not effect the photoelectric current produced. I disagree with this. If one source of light is used and an …
WebThe photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics.
