If two surfaces are in contact with each other, the contact between the two will help determine the ability for heat to transfer through conduction. Rougher surfaces will likely have less contact and transfer heat less effectively. Convection should not be affected much by this. If a surface is particularly rough or smooth, this may affect how much radiative heat it can absorb as well, but this is complicated, and depends on the size scale of the roughness.
The speed of light is normally about , miles per second, or fast enough to go around the world seven times in the wink of eye. Scientists succeeded in slowing it down to 38 mph. Well, not for light. From the perspective of a photon, there is no such thing as time. The speed of light is the speed at which all massless particles travel.
It is only happenstance that light was the first massless particle that we discovered, which caused c to be named after light, a name which has stuck. This is because time is like space, and moving objects are tilted in time. This case is sometimes called special relativistic time dilation. Light does not experience time. For a photon, time does not exist.
A photon emitted While the debate continues over whether travelling into the past is possible, physicists have determined that travelling to the future most certainly is. If an observer is approaching the origin, the relative speed of the light is faster.
Albert Einstein chose a synchronization convention see Einstein synchronization that made the one-way speed equal to the two-way speed.
