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.

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
