SUMMARY
The focal length of a plane glass is effectively infinite, leading to a power of zero. This conclusion arises from the behavior of light as it passes through a plane surface, where the rays remain parallel after refraction. The discussion emphasizes the importance of articulating the methodology behind such conclusions to enhance understanding and facilitate learning.
