Chromatic Aberration. A lens will not focus different colors in exactly the same place because the focal length depends on refraction and the index of refraction for blue light (short wavelengths) is larger than that of red light (long wavelengths).The amount of chromatic aberration depends on the dispersion of the glass. lens will not focus different colors in exactly the same place because the focal length depends on refraction and the index of refraction for blue light (short wavelengths) is larger than that of red light (long wavelengths).
Men's pole vault competition from the 1993 Athletics World Championships in Stuttgart, Germany. 3 men clear 5.90m with Sergey Bubka winning the competition with a 6.00m clearance on his first attempt. His jump at 5.90 was quite possibly the highest jump in the history of the pole vault.en's pole vault competition from the 1993 Athletics World Championships in Stuttgart, Germany. 3 men clear 5.90m with Sergey Bubka winning the competition with a 6.00m clearance on his first attempt.

Pole vaulting is a track and field event in which a person uses a long, flexible pole (which today is usually made either of fiberglass or carbon fiber) as an aid to jump over a bar.Pole jumping competitions were known to the ancient Greeks, Cretans and Celts. Pole: The fiberglass equipment used to propel the vaulter up and over the bar. 2  One side is more stiff than the other to facilitate the bending of the pole after the plant. 3  A vaulter may rest the pole on their arm to determine which side is the stiff side.
