Properties of Light - 12/10/2017

Specular Reflection:

- Specular reflection is a mirror-like reflection of light from a shiny, glossy or mirror surface. It is reflected from the smooth surface at a definite angle (reflection and angle are equal). The light will reflect from one single incoming direction into a single outgoing direction.

In the example above, the waves act as a mirror, so when the light hits the surface the mountain is reflected back onto the surface.

#layer 5 & 6. I think I need to do the upper section, #kalamataolives, over agai. And make the olives more upright and get the #specularreflection and #highlighting right (at Hudson River Valley Art Workshops)

specularreflection replied to your post:I didn’t know I was such a shitty person for...

I back your opinion regarding equality 100%.

You're fantastically rad and I'm glad to see that some people on here actually know the definition of that word
