1.10. A beam of light with \ = 660 nm is reflected off a surface. The incident beam is normal to thesurface. If 1% of its energy is lost in the reflection, what is the change in momentum of thereflected photons? How many photons must impact the surface per second if the intensity ofthe source is 3 × 104 W/m²? Find the total change in momentum affecting that surface.
