When light waves hit a rough surface they create a diffuse reflection. This means that the waves spread out in different angles.
a perfectly polished surface creates the most, follower by a rough surface, which is the more usual case.
Rough surfaces do create more friction than smooth surfaces. How much friction is created depends on how rough the surface is.
Surface tension, and upthrust. If the object is small and light enough, the force provided by the intermolecular bonding in the liquid will create a surface underneath the object, preventing it from sinking. An example of this is a skitterbug jumping across the surface of a pond. Upthrust is generated by the force of the liquids molecules bumping against the object. Upthrust is proportional to the amount of liquid displaced by the object.
You can increase the friction by increasing the roughness of the surface you are working on. Reduce the speed of the moving object, or increase the weight of the body you are working on. Increase the surface area of contact.
lithography
The top surface of an airplane wing is curved to create lift. Because of the curve, air has to travel farther across the top of the wing than across the bottom; this creates a low-pressure condition that pulls the airplane into it.
Calendering in papermaking is a finishing process that involves passing paper between heated rollers to create a smooth, glossy surface and improve its thickness uniformity and surface properties. This process can also enhance the paper's printability and opacity.
Tonal modelling is a means for the artist to create a sense of three-dimensional form in a painting. It involves using gradations of tone over the surface so that the lighter surface appears closer to the viewer and the darker side further away.
Asteroids and gravity create the surface features on the moon.

they dont. there are cetain benefits to lithographic prints, mainly economic, they can create multiples and sell them. obviously things like paintings and sculptures can fetch much higher prices but printmaking is also an art in itself. lithography and printmaking techniques allow for more accessible art.
One method of tennis court repair is crack sealing. It can prevent cracks from turning into something that needs major repairs. Seal coating is another method. Tennis court repair involves the leveling of the court and filling of any and all cracks to create a uniform surface. It also involves applying protection to the surface for durability.
Artists who use printmaking as a medium do so for several reasons. One of these is the type of images that they are able to produce by using a printmaking technique. Artists who use woodcut are able to get sharp contrasts between different tones by using that method. If they want work with a strong visual impact and a lot of energy, woodcut will give them that.Some artists also like printmaking because it allows them to produce multiple copies of their work. Albrecht Duhrer used printmaking for this purpose. He was able to share his work with a wider audience. Contemporary painters may produce limited edition high quality prints of paintings they have done for the same reason.
