Final answer:
The focusing distance of a newborn is approximately 46 cm (18 in.). This distance is sufficient for newborns to see objects within their visual range, such as their mother's face. Their vision is not fully developed and they have poor visual acuity, limited color perception, and depth perception.
Step-by-step explanation:
The focusing distance of a newborn is approximately 46 cm (18 in.) Newborns' vision is not fully developed, and they can only focus on objects directly in front of their face.
This distance is sufficient for them to see their mother's face and other objects within their visual range.
Newborns have poor visual acuity, limited color perception, and depth perception.
