Extended Response Questions 5 questions 15 marks Answer each component of the question, using terms, equations and concepts used through this course. Question 26 (3 points) As a radioactive fuel rod from a nuclear reactor is immersed in deep water, an intense blue glow is produced; this is the Cerenkoy effect, in which particles emit light when traveling in a material, at speed: v >c , where n is the index of refraction of the material. But it is impossible to exceed the speed of light. a) What does c represent in this equation? b) How is the Cerenkoy effect possible? c) What particle is most likely to be responsible for this? Question 27 (3 points) Explain why the wavelength of light decreases when it passes from a vacuum into a material. State which properties change and which stay the same. Question 26 options
