Radiation exerts pressure on surfaces on which it falls (radiation pressure).
(a) Will this pressure be greater on a shiny surface or a dark surface?
(b) For a given type of surface, will the pressure be greater using a bright source compared to a source emitting the same color but fainter?
(c) For a given surface, would you expect the force of radiation pressure on it to vary with distance from a light source? For all parts, clearly explain your reasoning.
