Homework Help: Help with optics radiation pressure problem

  1. Oct 15, 2005 #1
    Knowing that a 10 watt light source is used to illuminate a 1m(squared) area of glass surface with n=1.5 orthogonal to it's surface, how can i find the radiation pressure?

    Forum rules require you to show some working before we help you out.

    If you are completely stumped, you may want to review what the exact mechanism for radiation pressure is. Recall that Pressure is force per unit area. What might be responsible for imparting force on the glass surface? Can you suggest some quantities we might need to calculate before calculating the radiation pressure?
