Under what condition a convex lens when placed in a medium behaves as an ordinary glass plate?
A lens works by the difference in refractive index between the material in the lens and the surrounding medium. So a lens put in a medium that has exactly the same refractive index would not be a lens, it wouldn't bend light at all.
Whats the difference between thick and thin lens?
The diffrence between thick and thin lens depends on your precription for your eyes.
Will the focal length of glass lens change when dipped in liquid of refractive index equal to glass?
Everything a lens does is the result of the change of refractive index at its surface.If the lens is surrounded by a medium with the same refractive index as the glass,then there is no refraction (bending) of light at the glass surface, and the lens is nolonger a lens. If you could find such a liquid, you might not even be able to see thatthere's a lens down there in it.
What is the difference between converging lens and diverging lens?
converging lens show virtual and real images while diverging shows virtual images.
What is the difference property between convex and concave glass?
Convex lens converges the light and a concave lens diverges the light..
What is the difference between high index and polycarbonate lenses?
High-index lenses are an alternative choice to standard, plastic eyeglass lenses. Although high-index lenses are more expensive than plastic lenses, they can reduce the thickness and weight of an eyeglass lens, particularly for individuals with a strong prescription. High-index lenses are able to bend light to a stronger degree than a lens with a lower index, therefore the higher the index of the lens the less material needed to achieve a given prescription. High index lenses are categorized according to how strongly they bend light. The higher the index, 1.53 to 1.74 for high-index lenses, the better the lens is at bending light. High index lenses are 20 percent to 65 percent thinner than standard plastic lenses. In general, the stronger the prescription, the greater the difference in thickness between standard plastic and high-index plastic. A reduction in lens thickness and weight will occur in high-index lenses for prescriptions stronger than +2.00 or -2.50. Weaker prescriptions are not thinner than standard lenses when made with high-index materials. Polycarbonate lenses offer the same aesthetic benefits as high-index lenses, but polycarbonate lenses scratch easier, are difficult to coat or tint and are more likely to create distortions in colors and vision.

What is the relationship between radius of the lens and refractive index?
None. The radius of the lens depends on its shape, the refractive index depends on the material that the lens is made from.
What is the difference between lense and lens?
"Lense" is a misspelling of "lens," which is the correct spelling referring to a curved piece of glass or other transparent material that focuses or disperses light rays.
What is the difference between lens and lens?
There is none
What the difference between objective lens and the ocular lens when using a microscope?
the name
What is the difference between Oakley half jacket 2.0 and 2.0xl?
The lens size is the only difference the XL have a bigger lens.
What are oil immersion objective lens for?
because the oil have a refractive index near the glass one so we can work at high power without lossing any details by eliminating the air gap between the the specimen and the objective lens >>>> a.sh (iug)
Whats the difference between thick and thin lens?
The diffrence between thick and thin lens depends on your precription for your eyes.
What is the difference between Janssen's microscope and Leeuwenhoeks?
one is single lens and the other is multi lens
Who make better high index progressive lens Essilor or Zeiss?
Zeiss, quality product at reasonable price
What is the price different between 1.67 lens and 1.74 lens?
It's about a $300-400 USD price difference.
