Do thick concave lenses have longer or shorter focal lengths than thin concave lenses?
It have a shorter focal length because there is more time for the light rays to come together
Do thick convex lenses have longer or shorter focal lengths than thin convex lenses?
As a thicker lens has more material to do bend the light further it it would have a shorter focal length
Lenses are engineered to have specific focal lengths Besides the curvature of the two sides of a lens what determines the focal length?
The material that the lens is made from.
Why do convex lenses have shorter focal lengths than thin convex lenses?
The convex lenses are converging lens so when the curvature of the lens increases the focal length will decrease which helps when looking up close. A thin convex lens is for seeing things from a distant.
What is the importance of optic center for lenses?
It is the point from which all distances - object, image, focal length etc are measured.
Why do thick lenss show chromatic aberration but thin lenss do not?
because thick lenses have small focal length . this causes chromatic aberration. hence it can be minimised by increacing the focal length of lens or by using thin lenses which have high focal length.
How do you find the power of lenses using focal lengths?
Power (F)= 1/focal length (f) focal length f, is measured in meters the power, F, is in dioptres (D) In converging or convex lenses the power is positive In diverging or concave lenses, the power is negative :)
What are diverging and converging lenses?
Lenses enable individuals to view objects. A Converging lens has a positive focal length, which facilitates the convergence of the exiting rays. While, diverging lenses have a negative focal length, which facilitates the divergence of the exiting rays.
What is relation between focal length and radius of curvature in lenses?
The Center of curvature is 2 times the focal length. By the way this is a physics question.
Do thick concave lenses have longer or shorter focal lengths than thin concave lenses?

The material that the lens is made from.
Will the focal length of concave lens change in water?
no, because this happens only in the cases of lenses
Why do convex lenses have shorter focal lengths than thin convex lenses?
The convex lenses are converging lens so when the curvature of the lens increases the focal length will decrease which helps when looking up close. A thin convex lens is for seeing things from a distant.
What is a sentence with the word focal?
Wide-angle lenses have a short focal length. The focal character of my short story is a ten-year-old boy.
How you can find focal length of plane?
When light passes through the glass plate, the light doesn't bent so the focal length becomes infinity. And we have power=1/focal length, so power remains zero.
Which focal lenses make the best Samsung digital camera?
18-55mm focal lenses are very good lenses for the Samsung digital camera. Other good lenses for the Samsung digital camera are the 28-90mm and 35mm focal lenses.
