What happens to the image and magnifications as the object is moved?
As the object is moved closer to a converging lens or mirror, the image distance decreases, and the image becomes larger and more magnified. When the object is moved away from the lens or mirror, the image is formed farther away, becomes smaller, and less magnified.
Which objective is always used to first locate an object on a microscope and explain why?
The low-power objective lens (usually 4x) is always used first to locate an object on a microscope. This objective lens provides a wider field of view and a lower magnification, making it easier to find and center the specimen before moving to higher magnifications.
Has an objective lens that creates an image of the object which is enlarged by the eyepiece?
This describes a compound microscope, which usually consists of an objective lens that magnifies the image of an object and an eyepiece that further magnifies the image for viewing. This combination allows users to observe objects at higher magnifications with clarity.
What three objects do you need in order to magnify?
You need a lens, an object to view, and a light source to magnify an object. The lens will help in focusing the light and enlarging the object, while the light source will help illuminate the object for better visibility.
How does the object distance of a convex lens compared with the object distance of a concave lens?
The object distance of a convex lens is measured from the optical center to the object, while for a concave lens, it is measured from the optical center to the object along the path of light. In general, the object distance for a convex lens is positive, while for a concave lens, it is negative since the object distances are measured on the opposite sides of the lens.
What is the total magnifications of a microscope with a 45x objective lens and a 15x ocular lens?

What are the magnifications on the objective lenses?
There are many different microscopes currently on the market. Most of these microscopes come with different levels of magnification so that you can view an object in different ways. It is important to make sure the microscope you choose to use will have the correct maginfication you need.

What is the function of of objective lense?
used to view any object at different magnifications

In general, the object distance for a convex lens is positive, while for a concave lens, it is negative since the object distances are measured on the opposite sides of the lens.
What does a virtual image of a object look like through a concave lens?
A virtual image of an object through a concave lens is always upright, reduced in size, and appears on the same side of the lens as the object. Its location depends on the distance of the object from the lens and the focal length of the lens.
Which lens is the second lens that magnifies the object?
The eyepiece of the telescope doesn't magnify the object, but it does magnifythe real image of the object that forms at the focus of the primary lens or mirror.
What happens to an object when it comes closer to a convex lens?
When an object approaches a convex lens, the image formed can either be real or virtual depending on the object's distance from the lens. If the object is beyond the lens' focal point, a real image forms on the opposite side of the lens. If the object is within the focal point, then a virtual image is formed on the same side as the object.
What lens of a compound microscope is closest to the object being examined?
The 'object lens' in a compound microscope is closest to the object being examined.
