In a photoelectric experiment, the stopping potential is found to be 3.11 volts when light, having a wavelength of 1700 Å, is shone on a certain metal. (a) What is the work function of the metal? WebIf the wavelength is brought down from 6000 Å to 4000 Å in a photoelectric experiment then what will happen? The work frmction of the metal will increase ; The threshold frequency will decrease ; No change will take place ; Cut off voltage will increase; Validate Go to Question: Prev Question ...
WebThe threshold wavelength is dependent on the metal, and it is constant for each metal. 3. As the wavelength decreases for a specified metal, the speed (and thus the Kinetic Energy) of the emitted electrons increases. Conclusions from the Photoelectric Effect Experiment Observations such as these let to an important conclusion. WebA photoelectric experiment was carried out with a Sodium cathode with a clean surface. The work function this cathode is 2.75eV. The wavelength of the incident light on cathode …
WebSep 12, 2024 · An incident 71-pm X-ray is incident on a calcite target. Find the wavelength of the X-ray scattered at a 30°30° angle. What is the largest shift that can be expected in this experiment? Strategy. To find the wavelength of the scattered X-ray, first we must find the Compton shift for the given scattering angle, \(\theta = 30°\). WebMar 18, 2024 · You can show for yourself that the threshold wavelength is 459 nm (blue light). This means that if calcium metal is used in a light meter, the meter will be insensitive to wavelengths longer than those of blue light. Such a light meter would be insensitive to red light, for example. Exercise 1.3. 1
WebHe suggested that material particles can behave as waves and that their wavelength λ is related to the linear momentum p of the particle by λ = h / p. In 1927 Clinton Davisson and …
