2. {a} ChatGPT is a natural language processor {chatbot} based on articial intelligence. It was asked to explain in \"100 words or less what happens when an K-ray undergoes photoelectric absorption and how this affects beam intensityr as a function of distance. It was also asked to include one incorrect but plausible sentence in its answer. Here is the answer from ChatGPT: \"During photoelectric absorption, X-rays are absorbed by atoms, transferring their energyr to an inner-shell electron, which is ejected from the atom. The energy of the ejected electron during photoelectric absorption is always equal to the energy of the incident X-ray. This process reduces the intensity of the K-ray beam as it travels through matter, with the rate of attenuation depending on the distance travelled and the density and atomic composition of the material. As the beam trayels further, the number of photoelectric absorption eyents increases, leading to further attenuation." Identify the incorrect sentence. Explain why it is wrong and write out the sentence correctly based on your understanding of the photoelectric absorption process. {bi ChatGPT was asked to explain the effect of a certain phenomenon on an K-ray image without saying what that process is. Here is its response: \"When an K-ray beam passes through an object, some of the lit-ray photons are absorbed, and others pass through unaffected. However, some of the photons can interact with the electrons in the atoms of the object, causing a partial transfer of energy from the photon to the electron. As a result, the K-ray photon is deected in a different direction, which can cause blurring and a reduction in image contrast. This can make it difcult to distinguish between different tissues or structures in the X-ray image, and mayr result in an overall decrease in image quality.\" Which process was ChatGPT asked to explain? Describe one way to minimise the deleterious effects of this phenomenon on the quality of an X-ray image and briefly explain how this method works
