WebWrite two characteristic features observed in photoelectric effect which support the photon picture of electromagnetic radiation. Draw a graph between the frequency of incident radiation (v) and the maximum kinetic energy of the electrons emitted form the surface of a photosensitive material. ... The slope of the graph is equal to ... WebApr 9, 2024 · Energy-Frequency Graph for Photoelectric Effect. In the graph, we can see that the negative value or intercept of the energy-frequency graph gives the value of work function since work function is the amount of energy on an electron that is required to break it from the metal. At threshold frequency, energy will be zero and the slope of the ...

Webslope= y x = rise run slope= E f So the slope of the graph will always be Planck’s constant. Example 1: The following graph shows the effect of shining different frequencies of light … WebStep 3: Analyze the graph. Now, if we change the intensity of incident radiation, then h, c, e and ϕ 0 will not change. Therefore, neither the slope of the graph nor the y-intercept cut by the graph will change on changing the intensity of incident radiation. So, the graph will not change. Hence, option (d) is correct. foam under shower base

Photoelectric Effect - Toppr

WebIts validity is based on solid experimental evidence, most notably the photoelectric effect. The basic physical process underlying this effect is the emission of electrons in metals … WebAs shown in the graph below, electron energy increases with frequency in a simple linear manner above the threshold. All three curves have the same slope (equal to Planck's … WebThe photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons. It is important to note that the … foam unloading for low energy gas wells
