Lens exists in two forms, diverging, or converging. They affect light rays equally, but in contrasting manners.
The condenser adjusts the amount of light passing through the specimen.
Concave lens would diverge the rays.
The photons are absorbed by electrons that they encounter, then re-radiated onward. If the convex lens is in a medium of lower refractive index, the light converges on its way through, and emerges still converging.
Now suppose that the rays of light are traveling through the focal point on the way to the lens. These rays of light will refract when they enter the lens and refract when they leave the lens. As the light rays enter into the more dense lens material, they refract towards the normal; and as they exit into the less dense air, they refract away from the normal. These specific rays will exit the lens traveling parallel to the principal axis.
It depends on the lens. Assuming parallel rays entering the lens: Convex lens - they converge, Concave lens - they dinverge.
The light is delayed longer by the thicker part of the lens than by the thinner part of the lens. This results in the following:convex lens, light rays bend towards the axis of the lensconcave lens, light rays bend away from the axis of the lens
concave lens bends light rays away from the center
A lens that forms images by refracting light rays together is called what?
Light rays converge as well as diverge. it depends upon the type of lens or mirror you pass it through. A concave lens or a convex mirror diverges the light whereas a convex lens or a concave mirror converges the light rays!
They make the light rays converge to a point. Parallel rays converge at the focal point of the lens
Bi-Convex lens can be used to focus the Sun's rays
It is a lens that possesses at least one surface that curves outwards. It causes light to deviate inward, bringing the rays of light to a focus. Its thicker at its center than at its edges, and is used to correct far-sightedness. A convex lens is a lens that bulges outward on both sides. I have another comment. It does do all that stuff and who needed them to build a telescope? It's Galileo Galilie. Ohyah!
