What advantage does a larger lens have over a smaller lens?
A larger lens produces a brighter image than a smaller lens with the same focal length does. Another contributor added: A larger lens also gathers more light than a smaller lens does, enabling the viewer to see dimmer objects that they would be able to see with a smaller diameter lens, or the naked eye. The human eye reveals the light of stars down to 5th magnitude. A 2 1/2" lens reveals the light of stars down to 8th magnitude, and so on. To which the first contributor noted: It does all of that by producing a brighter image than a smaller lens with the same focal length does.
Focal distance of a concave lens is always what?
To my understanding of psychology, the lens convexity in distant vision is increased in order to better take in the visual stimuli. To focus visual stimuli on the fovea (focus point) of the retina, the lens undergoes a process of adjusting called "accommodation," and it becomes more convex to ensure that distant objects reach the retina. A failure to properly accommodate leads to nearsightedness (faraway objects falling short of retina) or farsightedness (nearby objects falling past retina)
An object with high volume and low mass has?
1. It has more gravitational force exerted on other objects 2. It holds more energy than smaller objects
How can you predict whether an object will sink or float?
The density of water is 1 g/cm cubed, and objects more dense that water will sink, while objects less dense than water will float. An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.
How does the thickness of a lens affect the focal length of a lens?
There are three factors affecting the focal length of a lens. 1. refractive index of the material of lens. 2. refractive index of the surrounding medium 3. the radius of curvature of the lens surfaces.
Does a microscope have more than 1 lens?
Yes they can have different magnification.
What microscope uses two of more glass lenses to magnify living or prepared slides?
All microscopes use more than 1 lens. A magnifying device with only 1 lens is called a magnifying glass.

What objects float in water?
objects that are less dense float to the top.
Which lens is greater than 50 mm?
a greater 1
How did the compound light microscope get its name?
it uses light to help you see the object and it has more than on lensIt uses light to see, and it is compound because it uses more than 1 lens.
A clouded lens is called?
Answer #1:presbyopia======================Answer #2:The clouding of the lens of the eye, either with age or in response to certainexternal influences, is called 'cataract'."Presbyopia" is the progressive loss of the ability to focus on nearby objects.
An object with high volume and low mass has?
1. It has more gravitational force exerted on other objects 2. It holds more energy than smaller objects
How much does 1 million weigh?
One million is a number, and as such, it is a concept rather than a physical object, and has no weight. You could weigh a million objects but you would have to say which objects they are; a million elephants weigh more than a million apples.

Why do Objects get bigger when you multiply scale by A number greater than one?
why do objects get bigger when you multiply/scale by a number greater than 1
