There is none
The diffrence between thick and thin lens depends on your precription for your eyes.
Diffraction = The amount of light passing through a photographic lens being adjusted by a diaphragm. Dispersion = The splitting of light of different colors due to the different indices of refraction at different wavelengths when the light enters a lens or prism.
optical axis passing through centeres of cornea,lens to retina.visual axis is line passing through fixation point to fovea.
Magnification is how large the lens system makes the object appear. Resolution is how sharply it can be seen at that magnification. In most optical systems, low magnification with high resolution is almost always preferable to high magnification with low resolution.
Besides shape, a converging lens can show real and virtual images, while a diverging lens can only show virtual images
A convex lens is wider at the edges than it is in the center. Therefore, it is a converging lens.
If a single lens forms a virtual image of an object, thenthe lens could be either a diverging or a converging lens.Which statement about a single thin lens is correctA diverging lens always produces a virtual upright image.
The function of lens is to to form an image of an object by converging or diverging rays of light from the object.
Yes. Nd converging lens = concave lens
Convex is always converging action and concave has diverging action.
If it is written as +2 Diopters it is positive, ie a converging lens. If it is written as -2 Diopters it is negative, ie a diverging lens. Diverging lenses are prescribed for myopia, or short-sightedness. Converging lenses are prescribed for hypermetropia or long-sightedness.
They can be either. They will converge if thicker in the middle than edges, and diverge if thinner in the middle than edges.
Lens exists in two forms, diverging, or converging. They affect light rays equally, but in contrasting manners.
