What lens gives an enlarged and erect image?
convex lens(converging lens)
Is magnification the ability to make things larger than what they are?
magnification is the ability to make things larger they they actually are by taking the lens from a microscope or by just using a microscope and magnifying the object.
What is the perimeter of 9.35 and 6.82?
Assuming that the shape is like the cross section of a convex lens, the perimeter is 16.17 units.
What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40 x and an ocular lens power of 10 x?
10 x * 40x = 400x
Why does a lens with with 2 cm diameter have 4 times the light gathering power of a 1 cm lens?
Because the 2cm lens has 4 times the area of a 1cm lens. (area = Pi*r2)
What is the positive lens is the same as?
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
What lens allows greater magnification on a microscope?
please help i need this question answered I believe a bi-convex lens, that is, a lens with an outward curve on both surfaces, would provide the greatest magnification in a simple (single) lens system.
A convex lens is also called a lens?
converging lens
What does binocular uses?
Binoculars uses lenses for magnification mainly. Two convex lens and prisms are used
What is a positive lens the same as?
A positive lens is also called a magnifying lens. It has convex surfaces and it has a measureable focal length where it produces an inverted image of a distant object. The power in dioptres is the reciprocal of the focal length in metres.
What type of lens are used in spectacles?
concave or convex lenses are used depending upon the eye power whether your eye power is positive or negative.
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.
What is a lens that is thicker in the middle than at the edges?
a convex lens
What kind of lens does a projector use?
projector have concave or convex
Do flashlights have convex or concave lens?
convex lens
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
Length of a lens is the distance from the center of the lens to its principal focus?
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
