Question
Chapter 10, Problem 15RA
Summary Introduction
To determine:
The term for the ability of the lens to increase its curvature and maintain a focus at close distances.
Introduction:
The human eye is associated with the sensation of vision. Humans are able to see near as well as the far objects. This is achieved by the alterations in the focal length of the human eye on their own. The focal length is adjusted by the alterations in the curvature of the lens of eyes.
