Question:

127 Double slit interference: photons Light with one wavelength is incident on a double slit barrier. The diagram illustrates
127 Double slit interference: photons Light with one wavelength is incident on a double slit barrier. The diagram illustrates the intensity of the light at various locations on a screen. The arrows indicate two locations, A and B, on the screen. a) Consider the statement: "A photon that arrives at A has more energy that a photon that arrives at B." Is this statement true or false? Explain Screen your answer. b) Suppose that in a short period of time 8000 photons arrive at A. Approximately how many will arrive at B during the same period of time?

Answers

a) the statement is false because all photons have the same wavelength all have the same energy

b) the intensity of light is proportional to the number of photons, hence the intensity at B is approximately half of that at A. Hence 4000 photons arrive at B
