Hi,
Plus l'angle définie entre la normale à l'objet analysé et le rayon lumineux émis est important, plus la quantité de lumière réfléchie, dans le cadre d'une réflexion diffuse, diminue
My attempt:
the more the defined angle between la normale with respect to the analyzed object and the emitted luminous ray is great, the more the quantity of reflected light, within the scope of a scattered reflection, lessens
I thought that "à la normale" was "perpendicularly" but I don't see how it could fit in this context
Any ideas?
Thank you

the angle between the ray of light and the normal to the object
Yes, it makes perfect sense: the 'normal' is the line sticking out perpendicular to the surface of the object, as you say; and what is of interest is the angle of incidence of the light, which is measured with respect to the normal, rather than the surface.

If the angle of incidence is 0°, i.e. the light is hitting the surface square on, then the illumination is maximum; as the angle of incidence increases, so the illumination falls off.

Thanks, Joanne! I've done quite a bit of work in optics... ;-)

: Yes indeed! Though I wonder why the inversion from "the angle between A and B" to "the angle between B and A"? Not that it makes any difference, of course...

Thanks, Chris! Just because I didn't like the sound of 'the angle between the normal to...'

: That's certainly an explanation, but not really the translation to fit in here, I think.
