What else can I help you with?
An object is placed in front of a converging lens in such a position that the lens f 14.0 cm creates a real image located 27.0 cm from the lens Then with the object remaining in place the lens?
if ur asking what is the position of the object, you can use this formulas 1/f = 1/di + 1/do f: Focul length (14 cm) di: Image Distance (27 cm) do: Object distance (?) Object Distance ( do) = 4.69 cm
If a telescope has an objective lens of 3 inches what is the focal length?
The size (diameter) of a lens does not determine its focal length. The amount of curvature of the lens does. Citing a diameter for a lens doesn't help us find the focal length. Lenses are ground to specifications that allow short or long focal length. The more curved the lens, the shorter the focal length. You can see this if we specify a given curvature and then start to "flatten" the lens. The focal length will get longer and longer as the lens is flattened. When the lens is flat (has to curvature) the lense has an infinite focal length, just like a piece of flat glass.
Would the ocular unit increase or decrease as magnification increases?
The ocular unit, which refers to the eyepiece in a microscope, remains constant in size regardless of the magnification level. As you increase magnification, the objective lens brings the specimen into closer focus without changing the size of the eyepiece. The ocular unit only magnifies the image produced by the objective lens, but does not physically change in size.
Why does a P look green?
A P may appear green due to chromatic aberration – a phenomenon where the eye's lens fails to converge all colors to the same focal point. This can result in a distortion of colors perceived by the viewer.
What are lenses with thick centers and thin edges called?
Lenses with thick centers and thin edges are called convex lenses. They converge light rays towards a focal point, which allows them to focus light and produce real images.
What image is produced on a converging lens when an object is twice as far as the focal point?
An inverted and smaller real image is produced by a converging lens when an object is placed twice as far as the focal point. The image is located between the focal point and twice the focal length from the lens.
Where must an object to be located for a converging mirror to produce a virtual image?
if the focal length is greater than the object distance from the lens
What factor determines the location and size of the image produced by converging lens?
The location and size of the image produced by a converging lens are determined by the object distance and the focal length of the lens. The image is formed on the opposite side of the lens as the object when the object is beyond the focal point (real image), and the size of the image depends on the object distance and focal length according to the lens formula.
A converging mirror has a focal length of 20cm Where should an object be placed so that its virtual image will be twice as tall as the object?
10cm
What is the focal length of a converging lens?
The focal length of a converging lens is the distance from the lens to the point where light rays converge after passing through the lens.
What is the focal length of a converging lens which produces a virtual image four time the size of the object the image being 15 cm from the lens?
Using the lens formula (1/f = 1/do + 1/di) and the magnification formula (m = -di/do) where m = -4, you can solve for the focal length (f). Given the object distance (do = -15 cm), you can calculate the focal length to be 10 cm.
Where is the only location where a converging mirror will not produce an image?
When the object lies within its focal length then no real image can be produced
What direction does a focal ray from an object proceed after passing through a converging lens?
After passing through a converging lens, a focal ray from an object will proceed through the focal point on the opposite side of the lens.
If the distance from a converging lens to the object is less than the focal length of the lens what willl the image appear to be?
C: virtual, upright, and larger than the object
What point of the converging lens can the object not be seen?
The object can't be seen at the focal point of a converging lens. This is because light rays from the object are focused at the focal point and don't diverge to form a real image.
What type of image do you get if an object is inside the focal point?
If an object is inside the focal point of a converging lens, the image will be virtual, upright, and magnified.
How does a converging lens bring an object inside its focal point into focus?
A converging lens brings an object inside its focal point into focus by refracting light rays that are parallel to the lens axis. These light rays converge at the focal point, creating a clear and focused image of the object.
