focal length formula
The focal length of an optical system is a measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated (parallel) rays are brought to a focus. A system with a shorter foc, This lesson explains the meaning of focal length and optical power, presents the equations to calculate these values, and gives an example for each...
