A
thick convex lens
has greater curvature or lesser focal length, whereas a thin convex lens has lesser curvature or greater focal length.
Which lens has greater focal length thick or thin?
Thick lens will have shorter and consequently
thin lens
will have greater focal length. Because, For a thick lens, the optical path length of the light is more, than for a thin lens, thus, the bending of light will be more in case of a thicker lens. Consequently, it has a shorter focal length.
Is a convex lens thick or thin?
A convex lens is shaped like two half circles,
thin at the edge and thick at the middle
. A convex lens is converging and can produce virtual and real images. A converging lens bends light inward so the light rays meet and form an image.
Which has more power a thick convex lens or thin convex lens?
A
thick convex
lens has more power than a thin one because it has greater curvature or lesser focal length than a thin lens.
Does focal length depend on thickness of lens?
They are the curvature (or radius) of the two lens coverings—besides the thickness of the lens and the refractive index of the glass. … So, focal length depends on
the radius of curvature
, the refractive index of lens material, and the medium’s refractive index in which the lens is placed.
Which lens has more power thick or thin?
A thick convex lens
has more power than a thin convex lens because it has greater curvature or lesser focal length than a thin lens. … Hence, the lens with a shorter focal length will have more power or higher refraction (causes more bending of light rays).
What is the greatest focal length?
The shorter the focal length (e.g. 18 mm), the wider the angle of view and the greater the area captured. The longer the focal length (e.g.
55 mm
), the smaller the angle and the larger the subject appears to be.
Where is convex lens used?
Convex lenses are used in
microscopes, magnifying glasses and eyeglasses
. They are also used in the cameras to create real images of objects present at a distance. The nature of the images depends on the way these lenses are used.
Does a convex lens make things bigger?
Lenses use these kinks to make objects look bigger or smaller, closer or farther away. A convex lens bends light rays inward, which
results in the object being perceived as larger or closer
. A concave lens bends rays outward; you get the perception that objects are smaller or farther away.
What does a convex lens look like?
Convex lenses
In a convex lens (sometimes called a positive lens), the glass (or plastic) surfaces bulge outwards in the center giving the
classic lentil-like shape
. … The focal point is on the opposite side of the lens to that from which the light rays originate.
Which lens has more power or?
A thicker lens
will be having more power because of the focal length of the thicker lens will be less as compared to the thin lens.
Which lens have more power?
The
convex lens
of smaller focal length (= 20 cm) has greater power since focal length is reciprocal of power.
Which converging lens has more power?
If a lens has a shorter focal length it is said to be more powerful. The power of a lens is defined as the reciprocal of the focal length. Lens power is measured in dioptres (D). Converging (
convex
) lenses have positive focal lengths, so they also have positive power values.
What is the difference between one lens and another that is more powerful than it?
Such a lens is called a
converging
(or convex) lens for the converging effect it has on light rays. … The greater effect a lens has on light rays, the more powerful it is said to be. A powerful converging lens will focus parallel light rays closer to itself and will have a smaller focal length than a weak lens.
Which lens is thicker in the middle?
A convex lens
can be defined as the lens which are thicker at the center and thinner at the edges whereas the concave lens can be defined as the lens which are thicker at the edges and thinner at the center. Convex lens is the converging lens whereas the concave lens is the diverging lens.
How does focal length depend on refractive index?
Now the focal length of a lens depends on the fact
that how much the lens can converge the light rays passing through it
. Therefore, the refractive index of the lens material affects the focal length because the refractive index tells us the amount of bending of light when it passes from one medium to another.
