Question

Difference between focus and focal point

Answer 1

FOCAL LENGTH

The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light.

FOCUS

Focus is the thinking skill that allows people to begin a task without procrastination and then maintain their attention and effort until the task is complete. Focus helps people pay attention in the midst of distractions and setbacks and to sustain the effort and energy needed to reach a goal.

For example, a child would be using good Focus skills when sitting down to begin an essay and then diligently writing until the assignment is done without getting distracted by the television, Internet, or friends.
