Longer focal lengths and less light rays are being bent. :) It's in the book.

What is the different between concave and convex mirror light?
Concave mirror would have the surface curved out get coated with mercury hence curved in surface would reflect the rays fallen on. But convex mirror would have the surface curved in get coated with mercury hence curved out surface would reflect the rays fallen on. Concave mirror would have both converging and diverging ability. When light coming from an object placed at a distance higher than its focal length right from the pole of the mirror, converging takes place. But the object lies in between pole and the focus diverging action. But in convex mirror irrespective of the placement of the object only diverging phenomenon. Concave mirror used as shaving mirror and dentists too use them Convex mirror is used as rear view mirror in case of vehicles near by the driver.
Which lens has a greater power convex lens of focal length 10 cm or a convex lens of focal length 20cm?
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
When do convex lens produce real image?
When the object length is less than the focal length
What is the power of a convex lens with 10cm focal length?
1.0 diopters
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.
Why the study was under taken of focal length of a convex lens by graphical method?
to determine the focal length of a convex mirror.
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!
What are plain shapes with length and width but no thickness?
All 2-dimensional shapes. They may be closed or open, concave or convex, made of straight lines or curved ones, the lines may or may not cross each other.

The length of a long curved line?
long
When do convex lens produce real image?
When the object length is less than the focal length
Why is the tubing on the brass instruments curved?
The tubing on the brass instruments is curved to get a long tube into a short length.
What happens to focal length when convex lens is cut horizontally?
no change
What is the power of a convex lens with 10cm focal length?
1.0 diopters
What happens to the focal length of convex lens when convex lens is cutted vertically along the optic center?
its focal lenght becomes 2f
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
