What is the name for the glass in a magnifying glass?
a lens..a converging lens to be exact
Why is it that in a pair of bifocal glasses the converging lens at the bottom and the diverging lens at the top?
It is a split screen usually the bottom part is cut as the (close up) lens the normal or larger part of the lens is normal- depending on whether one needs primarily distance or close-up correction, or for reading. the bottom lens group is usually secondary, not the main task. Franklin invented bifocal eyeglasses. He also devised the lightning rod, Franklin stove and *Long arm, lever device often used in grocery stores.

Benjamin Franklin
How does the lens of a light microscope make things look larger?
Look at your hand - 'end-on' and you see five finger-tips. The effect of the magnifying lens is to 'discard' the fingers to the left and right, and enlarge the image that remains in the center of the field of view.
What kind of microscope of lens curves outward like a sphere?
convex
Is an outward curving lens?
The outward curving of the lens is said to be a convex lens.
What lenses refract light outward and are thinner in the middle?
its a concave lens(:
How do you draw concave lens?
The shape of a concave lens is such that the middle part is thinner than the edge. If one side of the lens is flat, then the other side will be shaped inward like a cave, kind of like this: [( You can also have a concave lens where both sides are shaped inward, like this: )( You can even have a concave lens where one side is shaped outward, and the other side is shaped inward, as long as the inward-shaped side is more dramatic than the outward-shaped side.
Are concave lens outward curving lens?
yes
A lens that curves outward is called?
)( is a concave lens() is a convex lens
How are convex lenses and concave lenses the same?
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.
How does a lens magnifies an object?
A magnifying glass is a convex lens. A convex lens is a type of spherical lens. That means that the magnifying glass consists of two sides of glass and that it is thicker in the middle than the outer edges. The thickness is because the glass bows outward in the middle. The shape of the glass distorts the way we see the image on the other side.
A mirror or lens that curves outward is?
convex
Is the lens in a human eye concave or convex?
The lens of the eye is biconvex (convex on both sides).
How does the convex lens look like?
A convex lens curves outward, forming an elliptical shape.
How does a convex lens work?
A convex lens is curved outward on both sides. Also, a convex lens, is used to enlarge objects.
