Objective lenses are convex lenses.
They use convex lenses because they need to focus the light IN to the eye. Convex focuses in while concave spreads the light out. So, they use convex lenses.
Today's microscopes use convex lenses.
Compound microscopes usually have two types of lenses, the concave and convex. The concave is more of an hourglass shape, while the convex is more of a rounder shape.
Concave and convex lenses both enlarge an object to a certain extend.
A compound microscope has two lenses - the eyepiece lens and the objective lens. the objective lens(which is a convex lens) collects light and brings it to focus, creating an image. The eyepiece lens is placed at the focal point(the point at which light rays meetafter passing thru the convex lens). Thus we are able to see the magnified version of the image.
They are not the same. Convex lens bulge outward, and concave lenses go in ward. Convex lenses focus light, and concave lenses spread light out.
convex and concave
Maybe its "ocular".
i think they have convex lenses
Convex bulges outward (thicker in the center than the edge)Concave bulges inward (thinner in the center than the edge)Convex lenses magnify when you look through then, concave lenses make things look smaller.You can focus a distant object to a point with a convex lens (the image will be upside down).
They use convex lenses because they need to focus the light IN to the eye. Convex focuses in while concave spreads the light out. So, they use convex lenses.
yes
windows if u have a old camera or binoculars,u could open them up and get the concave and convex lenses from there.
Convex lenses are curved inward. Concave lenses curve outward.
Concave lenses curve inwardly.Convex lenses curve outwardly.* See related links.
They need a concave lens
Convex lenses protrude or curve out, concave lenses curve in, like a cave...
