I Lambertian surface

  1. Jul 11, 2017 #1
    Hello. I'm curious about the lambertian surface. Suppose in a given flat, surface of area A the light comes in, the incident angle being theta. The observer vector coincides with the light source, the angle between the normal of the surface being theta also.

    Then, when I calculate the radiant intensity, [w/sr^-1] should it be proportional to cos(theta)^2 or cos(theta)? Thanks.
