What lens gives an enlarged and erect image?
convex lens(converging lens)
A microscope has 20 X ocular eyepiece and two objective of 10 X and 43 X respectively?
lower power= 20 x 10= 200x higher power= 20 x 43= 860x
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
How factors affect the magnification of a convex lens?
The magnification of a convex lens depends on its focal length and the object distance from the lens. Increasing the focal length or decreasing the object distance will usually increase the magnification. The magnification is also affected by the size of the object being viewed and the optical properties of the lens itself.
Is concave lens having positive or negative magnification?
A concave lens produces a virtual image with a negative magnification. This means that the image is smaller than the actual object and appears on the same side as the object.
Why is concave lens called a negative lens?
A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
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.
Do convex lenses have negative focal length?
No, convex lenses have positive focal lengths. The focal length is the distance from the lens to its focal point where light rays converge. In convex lenses, parallel light rays are focused to a point on the opposite side of the lens, resulting in a positive focal length.
Is a microscope convex or a concave?
A microscope typically uses a convex lens to focus light and magnify an image. The convex lens converges light rays to produce a magnified image, whereas a concave lens would diverge light rays and not be suitable for magnification in a microscope.
Is a convex lens used as magnifying glass?
Yes, a convex lens can be used as a magnifying glass as it converges light rays to form an enlarged and upright image of an object placed closer to the lens. The magnification produced by a convex lens depends on its focal length and the distance between the lens and the object.
How does the object distance of a convex lens compared with the object distance of a concave lens?
The object distance of a convex lens is measured from the optical center to the object, while for a concave lens, it is measured from the optical center to the object along the path of light. In general, the object distance for a convex lens is positive, while for a concave lens, it is negative since the object distances are measured on the opposite sides of the lens.
Why focal length of convex lens is easier to find than a concave lense?
The focal length of a convex lens is easier to find than a concave lens because for a convex lens, the focal length is positive and is measured from the lens to the focal point. In contrast, for a concave lens, the focal length is negative and the rays of light are diverged. This makes it more challenging to find the focal point accurately.
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.
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 does binocular uses?
Binoculars uses lenses for magnification mainly. Two convex lens and prisms are used
