What is focal myelopathic changes?
Unhealthy changes in the spinal cord at certain spots.
What are subchondral cystic changes?
it is a fluid filled sac under the cartilage
Eye has fixed focal lengthThen how can you say that the focal length of changes?
The eye has variable focal length, its lense varies with thickness in order to focus to distant or nearby objects. Focal distance is constant, from lense to retina.
Explain how the focal length changes as a convex lens becomes flatter?
The focal length of a lens is the distance from the center of the lens to the point at which it focuses light rays. The bigger the focal length, the more powerful the lens. ChaCha!
How focal length of a lens change when apparatus immersed in water?
Yes , because when lens is deeped in water its R.I changes & hence focal length is increased
Why the focal length of concave mirror changes in water?
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
How the focal length of a convex lens changes as the sides of the lens become less curved?
Longer focal lengths and less light rays are being bent. :) It's in the book.
What do you call the point where light rays converge?
The focal point.Other answersWhen rays of light converge? I think it is called the "refraction." :)focal point ....would be preferredrefraction is more why it changes
How does the focal length of the human eyeball change?
The "eyeball" doesn't have a focal length, any more than the body of a camera or the tube of a telescope have. It's the lenses (or mirrors) in the eye, camera, and telescope that have focal lengths. In the eye, the focal length of the lens changes when the shape of the lens changes ... becoming flatter or thicker in the center. That change is accomplished by muscles around the circular edge of the lens. They stretch the lens to flatten it, and relax to thicken it, when you shift your focus to longer or shorter distances.
What do eye glasses do?
I'm pretty sure they just provide a glass median to change your eye's focal point. Since our eyes can get strained over time, which changes our focal point to become nearsighted or farsighted, glasses vary in thickness to compensate for the problematic focal point.
I was diagnosed with Poly cystic Kidney Disease at age 2 does that mean I have the recessive form?
no. It sometimes changes but not all the time
Does the focal length of mirror changes if it is immersed in liquid?
No. Light behaves the same way in the liquid as it would in the air (as far as reflection is concerned, so the focal length of a mirror would not change if it were immersed in liquid.
