Wheeler's Delayed-Choice Experiment
Wheeler's delayed choice experiment is a thought experiment in quantum physics that was proposed by physicist John Archibald Wheeler in 1978. The experiment is designed to explore the nature of wave-particle duality and the role of observation in quantum measurements. Case : A The experiment involves a setup where a beam of photons is directed towards a beam splitter at lower left corner. There is 50-50 probability that the photons will be transmitted (pass through straight direction to the bottom right mirror) or reflected (sent to the top left mirror). At beam splitter, if photon is transmitted, it is sent to the mirror which is placed at the lower right corner. It will reflect the photon to the top of the apparatus where screen - A is placed At beam splitter, if photon is reflected to the top left mirror, it will reflect the photon to the top right where screen - B is placed. In both cases we will find the path of the photon. Either it follows clockwise route or anti cl...
