He is using a parabolic reflector to amplify and concentrate light into a cathode ray tube from an old television. By focusing the light on the cathode ray tube, you can generate AC from the tube through a process known as the photoelectric effect. The photoemissive material inside the tube generates the free electrons as the result. #fyp #like #share #follow #science
