The law of reflection is quite useful for mirrors and other flat, shiny surfaces. (this sort of reflection is called specular reflection). however, you've likely been told that when you look at something, you are seeing light reflected from the object that you are looking at. this is reflection of a different sort: diffuse reflection. in this problem, you will see how diffuse reflection actually arises from the same law of reflection that you are accustomed to for reflections from mirrors.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
