Microscopes use lenses to magnify an image of a specimen placed on a slide. Light is passed through the specimen and the lenses to create an enlarged, detailed image that can be observed through an eyepiece or displayed on a screen. Some microscopes, like electron microscopes, use beams of electrons instead of light to create an image.

What happens when you move the iris diaphragm level while observing the field?

Adjusting the iris diaphragm level while observing the field of view can change the amount of light entering the microscope. Opening the diaphragm lets in more light, while closing it reduces the amount of light. This can affect the brightness and contrast of the image being viewed.


What kind of lenses does microscopes use?

Microscopes use two main types of lenses: objective lenses and eyepiece lenses. Objective lenses are placed near the specimen and magnify the image, while eyepiece lenses magnify the image further for viewing. These lenses work together to produce a magnified and detailed image of the specimen being observed.


What is the difference between an object and an image?

An image is an optical representation of an object.... Object is real... while image is not... i thnk the word imaginary fits for image.... we can take example of our shadow... when light falls on us ( object ) it creates an image (shadow ) in the ground....


How can you distinguish between a plane mirror concave mirror and a convex mirror by merely looking at the mirror?

If our image is real and inverted and smaller than the object ,then it is a concave mirror; if the image is virtual and erect and larger than the object,then it is a convex mirror; if the image is of the same size as of the object,it is a plane mirror. that is how we can distinguish or identify which of the given mirrors are what. BUT if the angle is very small you cannot tell Plane is flat, convex it curves outwards and concave it curves inwards.


What is the difference between Shadow and image?

A shadow does not show the details of the object whereas an image shows the exact details of the object.A shadow is formed due to blocking of light by an opaque object, while the image is formed due to reflection from an opaque, smooth and shiny surface.A shadow is always dark while the image shows true colors of the object.

Which transformation does not produce a congruent image?

A transformation that does not produce a congruent image is a dilation. While dilations change the size of a figure, they maintain the shape, meaning the resulting image is similar but not congruent to the original. In contrast, transformations such as translations, rotations, and reflections preserve both size and shape, resulting in congruent images.

How can you distinguish between a plane concave and a convex mirror without touching them?

One way to distinguish between a plane concave and convex mirror without touching them is to observe their reflected images. A concave mirror will produce an upright and magnified image of an object placed in front of it, while a convex mirror will produce an upright and diminished image. Another way is to look at the reflection of a distant object – a concave mirror will form a real image, while a convex mirror will create a virtual image.


What do compound microscopes focus light through to produce a magnified image?

Compound microscopes focus light through a series of lenses, including the objective lens and the eyepiece lens, to produce a magnified image. The objective lens collects and focuses light from the specimen, while the eyepiece lens further magnifies the image for viewing.

How does the thickness of a lens affect the size of an image?

The thickness of a lens affects the convergence of light rays, which in turn impacts the size of the image produced. Thicker lenses may cause more convergence, leading to a larger image size, while thinner lenses may produce a smaller image size.


What kind of image does a converging lens produce?

A converging lens produces a real or virtual image, depending on the location of the object with respect to the focal point. Real images are inverted and can be projected onto a screen, while virtual images are upright and cannot be projected.


What used to produce an enlarged image of a cell?

Microscopes are used to produce an enlarged image of a cell. Light microscopes use visible light to magnify the image, while electron microscopes use a beam of electrons to achieve higher magnification and resolution. Special staining techniques may also be used to highlight specific structures within the cell.


What is the difference between a slide and a negative?

A slide is a positive image mounted within a frame, typically used for projection onto a screen. A negative is an inverted image on a transparent film, used to create positive prints. Slides produce a direct positive image, while negatives require additional processing to create a positive image.


Is light microscopes use beams of electrons to produce magnified images?

No, a light microscope uses focused light (photons) to produce a magnified image. An electron microscope uses beams of electrons to create a magnified image.
