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)
When object is positioned at more than twice the focal length of a convex lens what are the properties of its image?
When the object is positioned at more than twice the focal length of a convex lens, the image formed is real, inverted, and smaller in size. The image is formed between the focal point and the optical center of the lens.
What is formula for concave lens?
The formula for a concave lens is the same as for a convex lens, which is given by the lens formula: 1/f = 1/v + 1/u, where f is the focal length of the lens, v is the image distance, and u is the object distance. For a concave lens, the focal length is considered negative.
What is the thin lens equation?
The thin lens equation is a relation that describes how the distance of an object from a thin lens, the distance of the image from the lens, and the focal length of the lens are related. The equation is given by 1/f = 1/do + 1/di, where f is the focal length of the lens, do is the object distance, and di is the image distance.
Does a microscope have more than 1 lens?
Yes, a compound microscope has more than one lens. It typically has two lenses: the objective lens and the eyepiece lens. The objective lens magnifies the specimen, while the eyepiece lens further magnifies the image for viewing.

What microscope uses two of more glass lenses to magnify living or prepared slides?
A compound microscope uses two or more glass lenses to magnify living or prepared slides. The objective lens closest to the specimen magnifies the image, and the eyepiece lens further magnifies the image for viewing.
Which lens is greater than 50 mm?
a greater 1

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
How can you predict whether objects will float or sink?
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.
What objects weighs less than 1 kg?
Butter milk
What would be brighter star than -1?
There is no such thing as a star with a magnitude brighter than -1. Negative magnitudes indicate brighter objects, with the most negative magnitudes corresponding to the brightest objects in the sky.
What objects float in water?
objects that are less dense float to the top.
