In 1949, Wasserman and Wolf devised an analytical means for describing the problem, and gave it an official name—the Wasserman-Wolf problem.
They suggested that the best approach to solving the problem would be to use two aspheric adjacent surfaces to correct aberrations.
They report that their technique can produce lenses that are 99.9999999999 percent accurate.
The researchers suggest the formula can be used in applications including eyeglasses, contact lenses, telescopes, binoculars and microscopes. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission.
The four kinematic equations that describe the mathematical relationship between the parameters that describe an object's motion were introduced in the previous part of Lesson 6.
The four kinematic equations are: In this part of Lesson 6 we will investigate the process of using the equations to determine unknown information about an object's motion.
The process involves the use of a problem-solving strategy that will be used throughout the course.
The strategy involves the following steps: The use of this problem-solving strategy in the solution of the following problem is modeled in Examples A and B below.
In his writings, he proposed that the effect occurs because the lenses were spherical—light striking at an angle could not be focused because of differences in refraction.
Isaac Newton was reportedly stumped in his efforts to solve the problem (which became known as spherical aberration), as was Gottfried Leibniz.
