Unformatted text preview: eventually hit by a neutron? (2) Using the same apparatus as in (1) but with electromagnetic radiation, is there a photon energy so low that parts of the screen will never be hit by a photon? If so, find the lowest energy so that all parts are hit. (3) Using the same apparatus as in (1) but with electromagnetic radiation, is there a photon energy so high that parts of the screen will never be hit by a photon? If so, find the highest energy so that all parts are hit....
