Which graph shows how intensity I varies with angle θ when electrons are diffracted by a nucleus? A B C D - AQA - A-Level Physics - Question 29 - 2018 - Paper 2

To determine the correct graph that represents how intensity I varies with angle θ during electron diffraction by a nucleus, we need to consider the wave nature of electrons and the expected diffraction pattern. The intensity typically follows a specific distribution, showing peaks at certain angles where constructive interference occurs. The graph that best represents this pattern is option A, which displays a clear single peak characteristic of electron diffraction.
