Light from objects that we see has to be focused by the eye to give a sharp image on the retina. Light from near objects is very divergent (spreading out), and the lens of the eye has to become very thick to focus it. As there is a limit to how thick we can make the lens, there is a near point beyond which we cannot focus.

What are objects that are viewed through a microscope placed on?
Objects that are viewed through a microscope are typically placed on a glass slide, which provides a flat and stable surface for the object to be observed. The slide is usually covered with a thin glass coverslip to protect the specimen and hold it in place while allowing light to pass through for magnification.
Name six factors that influence the visual weight of an object?
Size - Larger objects generally carry more visual weight. Color - Brighter or darker colors can affect the perceived weight of an object. Contrast - Objects with high contrast against their surroundings may appear heavier. Texture - Objects with more complex textures may seem visually heavier. Shape - Objects with more visually dominant shapes can have greater weight. Position - Objects placed closer to the center of a composition tend to have more visual weight.
If the pins in the following diagram were placed closer together the eccentricity of the ellipse being constructed would?
Assuming that the pins represent the foci, the answer is that the eccentricity would be reduced.
When was the first telescope built by nasa placed into orbit?
NASA's first telescope placed into orbit was the Orbiting Astronomical Observatory 2 (OAO-2), launched on December 7, 1968. It was the first of a series of orbiting observatories designed to study celestial objects without the interference of Earth's atmosphere.
A tool for seeing that has a tube with lenses a stage?
You are describing a compound light microscope. It magnifies objects through a combination of lenses (ocular and objective) and has a stage where the specimen is placed for viewing.
What is normal eye not able to see clealy the object placed closer then 25cm?
An eye works by taking the light that is coming from a point on an object and bending it so that it is all focused on single point at the back of the eye. The lens of the eye can only bend the light so much and the closer the object is the more the eye has to bend the light. If the object is closer than 25 cm it can't bend it enough.
Which type of force can a counter top provide?
A countertop can provide a normal force, which is the force exerted perpendicular to the surface of the countertop, supporting objects placed on it. This force prevents objects from falling through the countertop.
What forces are acting on all objects?
All objects are subject to the force of gravity, which pulls them towards the center of the Earth. In addition, objects may experience other forces such as friction, tension, air resistance, and normal force, depending on the situation in which they are placed.
How are objects placed in space?
By the use of rockets
Why are objects to be weighed placed on the center of a pan?
The objects to be weighed are placed on the center of a pan so they can be weighed accurately, without the pan tipping over.
Where do concrete words sit on the ladder of abstraction?
Concrete words sit at the bottom of the ladder of abstraction. They are specific, tangible, and easily understood, representing objects or ideas that are physical or can be perceived through the senses. Examples include objects like "table" or actions like "running".
How do objects behave when placed in water?
When objects are placed in water, they can sink, float, or stay suspended depending on their density and the density of the water. Objects that are denser than water will sink, objects that are less dense will float, and objects with a similar density may stay suspended in the water.
Where is dusclops in ss or hg?
In the safari zone when objects are placed.
Determines where content and objects are placed on a slide?
effect options
In what way is the atmosphere a challenge to viewing objects in space?
The atmosphere distorts light passing through it, causing objects in space to appear blurry when viewed from Earth. It can also absorb and scatter light, making it difficult to see faint objects or details clearly. This is why observatories are often placed in high, dry locations or in space to minimize the effects of the atmosphere on viewing objects in space.
Do convex lenses make things look bigger and smaller?
Convex lenses make objects appear larger when viewed through them. When an object is placed closer to a convex lens than its focal point, the lens will magnify the image. However, if the object is placed beyond the focal point, the lens will create a smaller, inverted image.
Why do objects have the same denisites?
because they have the same mass when placed in water
