d. Between 45% and 47% QUESTION 14 Not yet answered The principle of Frank and Hertz experiment is shown in the figure below. The experiment was performed with a low pressure neon and the excitation energy (E,-E) was found to be equal to 17 eV. The measurements were conducted using the following parameters: UH-8V,U, - 3V,U, -7 Vand the accelerating voltage U, can be varied from o V to Bov. We assume that the energy of the first maxima coincide with the excitation energy, so the potential difference phi - O ev. Marked out of 2.00 P Flag question ] U U. U, The principle of the Frank and Hertz experiment. If U - 70 V. How many neon atoms can the accelerated electron excites? Select one: a. 2 b.6 CB d.4
