An EM wave is directed at a solar sail made out of a dark absorbing material and applies a force on the sail that allows it to travel through outer space. There are no other forces on the solar sail, just the force due to the EM wave. How would the force on the sail change if the area of the sail is made 5 times larger and the sail is made out of a highly reflective material instead of a dark absorbing material?
