Radiation Pressure: Two light beams of different frequency but the same intensity fall on a black (totally absorbing) surface, striking perpendicular to the surface. Which of the following statements are true? (There could be more than one correct choice.)
A. The high-frequency beam exerts more pressure on the surface.
B. Both beams exert the same pressure on the surface.
C. If the surface were painted white (totally reflecting), the pressure on it would be less than when it was black.
D. Painting the surface white would not affect the pressure on it due to these beams.
E. The light beams exert no pressure on the surface because light is just energy.
