Figure 13From: Cassini/VIMS observes rough surfaces on Titan’s Punga Mare in specular reflectionGreat salt lake. Two photos taken sequentially a few seconds apart looking out the right-hand window while flying southbound on approach to Salt Lake City airport. In the photo at left, the specular point lies within an arm of the Great Salt Lake. Extending above and below the specular point is an area of enhanced wave activity, also showing specular reflection due to its surface roughness. However the area to the left of the specular reflection is wave-free. At right the specular point has moved into that wave-free zone. Now the mudflats to the upper-left of the specular point are starting to show increased specular flux due to their own roughness.Back to article page
