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.

In the heaviest dead lift recorded, British weightlifter Andy Bolton lifted 457.5 kilograms from the floor to his thigh. Strongmen like Bolton are perhaps five or six times stronger than the average man, who will often struggle to lift 45 kilograms over his head, says Dan Wathen, an athletics trainer at Youngstown State University, Ohio. The record for an overhead lift is 263.5 kilograms.
