A narrative essay is a type of essay that tells a story, usually from the writer's personal perspective. Narrative essays can be about a wide range of topics, as long as they have a clear plot and a central theme. Here are some ideas for things to write a narrative essay about:

  1. An important event or experience from your life: This could be something that had a big impact on you, like a trip you took, a challenge you faced, or a moment of realization.

  2. A person who has had a significant influence on you: This could be a family member, a friend, a teacher, or anyone else who has made a difference in your life.

  3. A place that holds special meaning for you: This could be a place you've visited, a place you've lived, or a place you've always dreamed of going.

  4. A time when you faced a difficult decision: This could be a decision that affected your life in a big way, like choosing a career path or moving to a new city.

  5. A memorable moment or experience with a friend or loved one: This could be a time when you laughed, cried, or learned something new together.

Remember, a narrative essay should have a clear plot, with a beginning, middle, and end, and it should have a central theme or message that ties everything together. As you brainstorm ideas, think about what you want to say and what you hope your readers will take away from your essay.

Parts of a Microscope and Their Functions

components of microscope and their function

Objectives are responsible for primary image formation and play a central role in establishing the quality of images that the microscope is capable of producing. Also called a revolving nosepiece or turret. Helps to magnify the image of specimens. These separate optical channels enable stereo or three-dimensional images of the specimen. The total magnification of the microscope is the product of the magnification of the objective lens and the eyepiece. Light microscopy has a number of applications in different sectors including in gemmology, metallurgy and chemistry.

When carrying a compound microscope always take care to lift it by both the arm and base, simultaneously. As discussed above, the magnification factor of the specimen is calculated by considering the distance between the specimen and the objective, and the front focal length of the objective lens system F Objective. He used a single lens to create a simple microscope that was able to magnify objects up to about 200 times their actual size. Arm : The part of the microscope that connects the eyepiece tube to the base. With this microscope you can get high resolution images of both biological and non-biological specimens. These lenses, along with a light source, allow scientists, technicians, and students to get an up-close view of samples. Phase Contrast Microscope Phase Contrast Microscope is a microscope that is used to observe the structure of micro-sized living things such as animal tissue or bacteria without using dyes.

The condenser is a lens system located below the stage that focuses the light onto the specimen. Using a stereo microscope, one can observe and analyse the three-dimensional structure of an object. It is usually equipped with stage clips, which are used to hold the specimen in place, and a stage aperture, which is an adjustable opening that controls the amount of light that passes through the specimen. It is usual that when we study the cells, we need a microscope for this. Most compound microscopes are parfocal. This allows the visualization of cells and cell components that would be difficult to see using an ordinary light microscope.

The microscope has two sets of objectives with a single set of eyepieces monocular or binocular , often used in forensic science. It is typically equipped with a range of mechanical and electrical controls that allow the specimen to be moved and positioned as needed. The mechanical standard is 1 diameter, 32 TPI threads per inch , male on the lens and female on the camera. Diaphragm: Diaphragm is used to vary the intensity and size of the cone of light that is projected upward into the slide. Mechanical Stage : A flat mechanism that sits on top of the stage and allows the viewer to move a specimen small distances - a task that is otherwise difficult at higher magnifications. Since different colours of light bend at different angles, an achromatic lens is made of different types of glass with different indices of refraction.

Today, microscopes are used in a wide range of scientific and medical fields, including biology, medicine, and materials science. Compound microscopes use three lenses are used to accomplish the viewing, the eyepiece lens, condenser lens and objective lens. A light microscope is a biology laboratory instrument or tool, that uses visible light to detect and magnify very small objects, and enlarging them. Most modern microscopes are modular in the sense that the same body can be used with different bases and vice versa. There is a minimum magnification necessary for the detail present in an image to be resolved, and this value is usually rather arbitrarily set as 500 times the numerical aperture 500 × NA. Since different color light refracts at different angles, an achromatic lens is made of different types of glass with varying indices of refraction. These parts include: 1 Eyepiece: An eyepiece, or ocular lens, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes.

You will be able to look up information on a specific part you are encountering issues with and figure out how to rectify the issue. Illumination System : The light source on light microscopes, typically mounted under the stage except on inverted microscopes. Note: The fine adjustment knob is utilised for all focusing when using high-power lenses and to bring the specimen into sharp focus when using low power. Sub-Stage : The parts of the microscope below the stage, including the illumination system. In Figure 5, the second characteristic ray is illustrated as a yellow-filled dotted line passing through the front focal point F' of the lens. Slip Clutch : A mechanical device on the focusing knob that allows the knob to "slip" if a viewer keeps turning the knob beyond its range of travel. It is typically made of metal or plastic and is used to hold the microscope in place while it is being used.

What two features of a microscope are essential for a microbiologist? A drop of oil is placed on the cover slip and the objective is lowered until it touches the oil. It is especially important when viewing thin or transparent specimens, as it can help to improve the contrast and resolution of the image. If your microscope has a mechanical stage, the slide is controlled by turning two knobs instead of having to move it manually. There are several different types of microscopes used in light microscopy, and the four most popular types are Compound, Stereo, Digital and the Pocket or handheld microscopes. How are the functions of a microscope dependent on each other? A Microscopes are made up of two parts, the holding part which supports the microscopes and its components, and the optical part which is used for magnification and viewing of the specimen images. It is used with the high­ power objective to bring the specimen into better focus Illuminator Light Source : light sources for Microscope.

Stages are often equipped with a mechanical device that holds the specimen slide in place and can smoothly translate the slide back and forth as well as from side to side. It fits into a trinocular port. Scanning probe microscopes and electron microscopes are commonly used to study the properties of nanomaterials. The objective lens projects a real and inverted image of the magnified specimen into the intermediate image plane of the microscope Image Plane 3 , which is located in the center of the eyepiece field diaphragm at a fixed distance behind the objective. Through the eyepiece, you can visualize the object being studied. This prevents the objective lens from being too close to the specimen slide, which could cause damage.
