let me draw more of the light source, so rays coming in, and rays coming in from our light source but every point of the apple is also having this diffuse reflection which is reflecting only the red part of the spectrum, it's absorbing all of the other parts of the spectrum and, so what you see is, that point where you're getting the pure specular the pure specular reflections, that's the point that looks shiny where you can kind of see the light source and from every other point on the apple, where only this guy right here's only getting the diffuse red light and that's why, if you move the apple, or actually even better, if you move where you're looking at the apple that, point of reflection's gonna look, like if I start looking at it from this direction
