The answer is Convergence of images behind the Retina
Convex lens converges light to a principal focus. The thickness of the lens determines the focal length (distance between the center of the lens and the principal focal point). Therefore, by evaluating the thickness of the convex lens, farsightedness, (an eye defect of convergence of images behind the retina) can be corrected by enabling images in the eye to form behind the retina.
Physical is something you can have/ hold and mental is something in ur head that you can't see or hold.
Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. The air rises, clouds form and grow into narrow band that produces 2 to 3 inches of snow per hour or more.
<h3>
Which are the key factors in lake snow affect?</h3>
Wind direction is a key component in determining which areas will receive lake effect snow. Heavy snow may be falling in one location, while the sun may be shining just a mile or two away in either direction.
The physical geography of the land and water is also important.
