23.68. Set Up: For a totally absorbing surface the radiation pressure is Solve: A 1 kg mass has a weight of 9.8 N. The force the light beam exerts is much too small to be felt by the man. 23.69. Set Up: For absorption the radiation pressure is where and Solve: (a) (b) The average pressure is (c) f is the same in the air and in the vitreus humor. (d) 23.70. Set Up: The general wave function for the electric field is and Solve: (a) By comparing the equation for E to the general form, and (b) (c) In air, the same as in the plastic. so The equation for E in air is 23.71. Set Up: Solve: Reflect: This value of is similar to the electric field amplitude in ordinary light sources.
