How many convex lens does compound microscopes have?

A compound microscope has2 convex lens.

Factors affecting for length of a convex lens by the lens displacement method using cojugate foci?

There are many factors that can affect the focal length of a convex lens. These include: - The thickness of the lens - The type of material that the lens is made ot of - The curviture of the lens - How big the distance between the lens and the image you are viewing is. This is obviously a major factor due to the fact the the focal length is where all the light becomes concentrated and the image becomes clear as pristine. I hope this has helped those seeking the answer to the question above. I know this information as I am doing a controlled assessment all about 'How Factors Affect The Focal Lenght/ Point Of A Convex Lens'. Thankyou for viewing. Samia :)

How many types of lenses to compound light microscopes have?

Compound light microscopes have two types of lenses: objective lenses and eyepiece (or ocular) lenses. The objective lens is located close to the specimen and magnifies the image, while the eyepiece lens further magnifies and helps focus the image for the viewer.

How many flat or curved surfaces are on a lens?

It depends on the uses the lens are going to be put to. A lens may have a convex front and a flat back, or a convex front and a concave back, or even a convex surface on both front and back. Or even concave on both the front and back.Concave means bowed inwards.Convex means bowed outwards.

What lens makes light refract and spread out?

LensesThe phenomenon of refraction of light has found usage in many devices. Lenses are the most popular ones. Especially, cylindrical lenses. Cylindrical lens is a piece of transparent material where the lines representing the surfaces are arcs of circles or one is arc of circle and the other is flat. The line passing through the center of the lens and on which the centers of the two spheres are located is called the axis of lens. The point on this axis at which incident parallel rays focus or converge is the principal focus F. The distance of the principal focus from the center of the lens is known as the focal length, f.Figure 15 F - principal focusf - focal lengthThe ray parallel to the axis is bent by the lens so as to pass through the principal focus. It follows from the reversibility of light paths that the ray that passes through the focal point must travel parallel to the axis after it has passed through the lens.Figure 16 Reversibility of light paths, rays sent from the principal focustravel parallel to the axis after they have passed through the lens.Images formed by lensesLenses form real and virtual images. Real images are formed when the object is located farther than the principal focal point. The real image can be made visible by placing a screen on one side of the lens and the object on the other. Real images are always upside down. If the object is far from the lens then the image is close to the lens and is smaller than the object, if the object is located near the lens then the image is formed far from the lens and is bigger than the object.Figure 17 The real image of candle is formed on the screen. Its size depends on the distance of the object from the lens.Figure 18 The real image, upside down, smaller than the object.Figure 19 The real image, upside down, of original size.Figure 20 The real image, upside down, bigger than the object.Virtual images are formed when the object is placed between the principal focal and the lens. You can see it by looking straight at the lens.Figure 21 The virtual image, straight, bigger than the object.

What is the advantage of using a concave mirror in the place of convex lens as objective in a telescope?

-- The lens must be transparent. The mirror must only be solid. -- The lens must be perfect through and through. The mirror only needs a perfect surface. -- The lens needs two perfectly shaped surfaces. The mirror needs only one. -- The lens can be supported only around its edge. The mirror can be supported at as many points across its back as desired.

How many lenses does the human eye have?

The human eye typically has one lens, which is located behind the iris. This lens helps to focus light onto the retina at the back of the eye, which then sends signals to the brain for processing visual information.

How convex lens is a converging lens?

The fact that we observe in case of refraction through prism is, the ray gets bent or deviated towards the base of the prism. So in case of a convex lens you can imagine many prisms have been packed one above the other in the upper half portion and they are packed in the inverted position in the lower half. So as parallel beam of light rays enter through these prisms all get deviated towards the base and hence the rays get converged on the other side. Thus theonly ability of a convex lens is just to converge.1) already converging rays after passing through a convex lens get more converged2) parallel rays falling come out converged3) already diverging one will go less diverged.4) So there is chance for diverging rays after refraction through lens come out parallel.

Why the eyes can still form an image after the lens has been removed by a surgery?

After lens removal surgery, such as cataract surgery, the eye can still form an image because the cornea and the retina are intact and functional. The cornea helps to refract light, focusing it onto the retina, which processes visual information. While the absence of the lens affects the eye's ability to focus light sharply, many patients can still perceive images, often with the aid of corrective lenses or intraocular implants. Thus, the basic mechanisms of vision remain operational even without the natural lens.

How many light rays are required to locate the image formed by a lens?

2 is the minimum number of light rays required to locate the image (of a point object) formed by a lens. First find the path of rays after refraction and then their point of intersection gives the location of the image.

Does a convex lens split the white light into a spectrum of colored light?

Yes, a convex lens can disperse white light into its constituent colors by refracting different wavelengths of light by different amounts. This phenomenon is known as dispersion, and it can be observed through a prism or a convex lens.

What are the disadvantages of convex mirror?

Convex mirrors reflect images in a distorted shape due to their convex shape. It can be difficult to determine the actual placement of objects.Since versions of convex mirrors are found in many vehicles, driver's misjudgment of speed and miscalculation of distances can be a direct result of the curvature of the mirror within the car.
