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 is the clearest image produced by a lens?
The clearest image produced by a lens is obtained when the lens is properly focused and there is no aberration, distortion, or other optical imperfections. This results in a sharp and clear image with accurate representation of details and minimal blurriness. The clarity of the image is influenced by factors such as the quality of the lens, the aperture setting, and the distance between the lens and the object being photographed.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
Do binoculars have convex lenses?
Yes they do. They also include concave mirrors and a plane mirror.
How and when is the image inverted?
Whenever a real image is formed by a real object,the image is always inverted. for eg when light rays from infinity falls on convex lens it forms a real and inverted image at focal plane.
The image produced by a convex lens depends on what?
The image depends on the distance the object is from the lens.
What kind of image is formed by a convex lens when the object at infinity?
The image produced is a real image if the object is located at infinity and the lens is a convex lens. The produced image can actually be placed on a screen and photographed.
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.
Explain how an image produced by a convex mirror is similar to an image produced by a concave lens?
An image produced by a convex mirror and an image produced by a concave lens are both virtual, erect, and diminished. They both form on the same side as the object and the images appear smaller than the object itself.
If the image produced by a lens is the same size as the object then the lens must be?
A diverging lens. In this case, the object distance will be equal to the image distance but with opposite sign.
Is the type of image formed by a convex lens depend on the location of the object relative to the optical axis?
No it isn't, because the type of image a convex lens forms depends on where the object is relative to the focal point of the lens.
What is image called produced by convex lens?
The image produced by a convex lens is called a real image if it is formed by converging light rays that actually intersect, or a virtual image if it appears to be formed by diverging light rays that only appear to intersect when traced backward.
What does the image formed by convex lens depend upon?
The image formed by a convex lens depends on the object distance from the lens, the focal length of the lens, and the object size. These factors determine whether the image formed is real or virtual, magnified or diminished, and upright or inverted.
Does convex lens produce real image?
No, convex lens does not produce a real image. It reflects the real image
If an object is placed at a distance greater than twice the focal length of a convex lens what type of an image will be produced?
If an object is placed at a distance greater than twice the focal length of a convex lens, a real and inverted image will be produced. The image will also be smaller than the object.
What are the Lens that can create a real or virtual image?
Lenses that can create a real image include converging lenses such as convex lenses. Lenses that can create a virtual image include diverging lenses such as concave lenses. The type of image formed depends on the focal length and the object distance from the lens.
When an object is at infinity from a convex lens what will be the image?
When an object is at infinity from a convex lens, the image will be formed at the focal point of the lens. The image will be a real and inverted point of light.
