To identify: Whether the lens move closer to the sensor or farther away to focus a given object.
Answer to Problem 35SSC
The lens move closer to the sensor to focus a given object.
Explanation of Solution
Introduction:
An optical lens or combination of lenses are used in a camera in order to focus and produce a clear images of an objects which are at a distance. In other words, these are designed to diverge or focus light.
The real image of an object is always formed at a distance far from the lens. If the object is farther away, the image is closer to the focal point. Hence the lens should be moved closer to the sensor in order to focus on a tree which is farther away.
