How is the strength of an electric field indicated with electric field lines?
Given a positive charge the electric field lines are drawn starting from the charge and pointing radially outward, ending in principle at infinity, according to the electric field strength being proportional to the inverse square of distance. From the definition of electric field we know that the modulous of the electric field is greater for smaller distances from the field generating charge. Since the electric field lines point radially outward we consider the density of lines an indication of the strength of the electirc field. If we immagine to trace a circle around the electric field generating charge, of radius slightly greater than the radius of the object which holds the charge and therefore generates the electric field, such circle will be crossed by a number 'n' of lines. The density of lines crossing the cirle will then be the circumference of the circle divided by the number 'n' of lines. For a larger circle we will have a greater circumference, but same number of lines 'n', and therefore a smaller density of lines crossing it, which idicates a lower intesity of electric field for a greater distance from the charge.
What are synonyms for compass?
range, field, area, reach, scope, limit, extent, boundary
What materials has permeability's slighter greater than that of free space?
Materials with permeability slightly greater than that of free space include certain ferromagnetic materials, such as soft iron and some alloys, which have a relative permeability greater than 1. Additionally, paramagnetic materials, like aluminum and certain rare earth metals, also exhibit permeability values that exceed that of free space, albeit to a lesser extent. These materials can enhance magnetic field lines but do not retain magnetization once the external field is removed.
What is apature?
Aperture refers to the opening in a camera lens through which light passes to reach the camera sensor. It is measured in f-stops, with a lower f-stop indicating a larger aperture and more light entering the camera. Aperture size also affects depth of field, with larger apertures creating a shallower depth of field and smaller apertures creating a greater depth of field.
What are symbols that evaluate each field value to determine if it is the same or in between a range values as specified by the criteria?
less than (<) and greater than (>)
Does low power or high power have a smaller field but magnifies to a greater extent?
Low power magnifies to a smaller extent and has a wider field of view, while high power magnifies to a greater extent but has a smaller field of view.
Which of the objective have a smaller field but magnifies to a greater extent?
In microscopy, the objective lens with a smaller field of view but greater magnification is typically the higher-power objectives, such as the 100x oil immersion lens. These objectives provide a narrow field of view but allow for detailed observation of smaller structures due to their higher magnification capabilities. This trade-off is essential for examining intricate details in specimens, such as cellular structures or microorganisms.
Why is the depth of field greater and the image sharper when a camera lens is stopped down to a larger f-number?
See the answer to "Why do you get a greater depth of field from a smaller aperture"There's also a great article on it at: http://www.uscoles.com/depthoffield.html
What happens to the field of view as magnification increases?
As magnification increases, the field of view generally decreases. This is because higher magnification typically focuses on a smaller area in greater detail, limiting the overall visible area in the field of view.
What is an electromagnetic wave affected by?
Electrical field - to a large extent. Gravity - to a lesser extent.
Which magnification provides the largest fov?
The lower magnification provides the largest field of view (FOV). When you increase magnification, the field of view decreases, allowing you to see a smaller area but with greater detail.
Do all planets have the same gravitational field strength as earth?
No, the gravitational field strength on each planet depends on its mass and radius. For example, Jupiter has a stronger gravitational field than Earth due to its larger mass, while Mars has a weaker gravitational field because it is smaller and less massive than Earth.

What happens to Field of View when you change from low power to oil immersion high power?
When you change from low power to oil immersion high power on a microscope, the field of view decreases. This is because high power objectives have a narrower field of view due to higher magnification, leading to a more detailed but smaller area being visible through the lens.
Why to start with 4x objective rather than higher power?
Starting with a 4x objective allows for a larger field of view and greater depth of field, making it easier to locate and focus on the specimen. Higher power objectives have a smaller field of view and shallower depth of field, which can make it challenging to find and keep the specimen in focus.
Why does high power magnification change the area of the slide?
High power magnification narrows the field of view, focusing on a smaller section of the slide. This can create the illusion that the overall area of the slide has decreased, when in fact it is just a smaller portion that is being observed in greater detail.
The greater the mass of an object the greater the objects?
acceleration will be when a force is applied to it. This relationship is described by Newton's Second Law of Motion, which states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This means that a larger mass will require a greater force to accelerate at the same rate as a smaller mass.
