Does fresnel lens is a convex lens?
yes...it is a plano-convex lens....wid grooves cut in it on convex side...it is very very thin as compared to a simple convex lens
Which lens is a converging lens a double-convex lens or a spherical-convex lens or a plano-concave lens or a convexo-concave lens?
Your are mixing properties. Converging lens is always thicker in the centre and thinner at the edges. The other cathegory is the geometry of shape of the surfaces of the lens. Convex means that the shape is similar to the outer surbace of a sphere, concave means that the shape is similar to the iner surface of a sphere (or: convex = lower side of a spoon as we use it for sampling a soup; concave: upper (inner) shape of the spoon). A double convex lens is always a converging lens. A plano-concave lens is always a diverging (not converging) lens. A convexo-concave lens is the most usual shape of a lense used in spectacles. It can be either converging or diverging, depending on the radii of the surfaces.
What is a double-convex lens work?
with the help of convex lens we are able to converge the beam of rays to the fix point.
Is the lens in a human eye concave or convex?
The lens of the eye is biconvex (convex on both sides).
What is the difference between double convex lens from double concave lens?
Convex lens give a virtual & diminished image while concave lens give inverted virtual in rare case & magnified image.
Which of the following lenses is a converging lens A double-convex lens B spherical-convex lens C plano-concave lens D convexo-concave lens?
Double-convex lens
What lens is a converging lens double-convex spherical-convex plano-concave or convexo-concave lens?
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
Are plano lens convex?
No - by definition. You can have a plano-convex (or -concave) lens (one side flat). Actually a purely plano "lens" would be merely a glass disc.
Howdoes plano convex lens make fringes circular?
A lens that only has one flat surface is called a plano convex lens. The plano convex lens makes fringes circular because the air film is symmetrical.
Does fresnel lens is a convex lens?
yes...it is a plano-convex lens....wid grooves cut in it on convex side...it is very very thin as compared to a simple convex lens
Name two lenses used in stage lighting instruments?
There are a variety of lenses used in theaterical or stage lighting. Here is a short list and their uses: Plano-Convex- This lens is used in standard Ellipsoidal Spotlights. One side is flat(plano) and the other is Convex. Convex-convex- This lens is also used in conjunction with Plano-Convex. This, however, has both sides of the lens as convex. Fresnel lens- Used in fresnels to disperse the light Par- These lenses are intergrated into the filament, envelope, and base of the lamp. These are bubble type lenses.

What type of lens is used in a hand lens?
double convex

What did the microscope Zacharias Janseen invent look like?
It was a tube with lenses at each end. The magnification ranged from 3X to 9X depending on the size. The eyepiece lens was bi-convex and the far end lens was plano-convex.
