WHere are two lenses locate do in a compound microscope used in most classrooms today?
In most classrooms today, a compound microscope typically has two lenses located within the eyepiece and the objective. The eyepiece lens (or ocular lens) is located at the top of the microscope and is used to view the magnified image of the specimen. The objective lens is located near the specimen and is responsible for magnifying the image of the specimen before it reaches the eyepiece.
What else can I help you with?
Why is it desirable for microscope lenses to be parfocal and parcentric?
Microscope lenses that are parfocal and parcentric allows the user to changed between lenses will keeping the speicemen focused and centered, instead of having to adjust the x, y or z plane (i.e. focus and the stage).
Do wasps have eyes and how do they use them to navigate their surroundings?
Yes, wasps have eyes. They use their compound eyes to detect movement, locate food, and navigate their surroundings. These eyes are made up of many tiny lenses, allowing them to see a wide field of view and detect fast movements.
When viewing a specimen under the microscope you should always start with what?
When viewing a specimen under the microscope, you should always start with the lowest magnification objective lens. This allows you to locate and focus on the specimen before moving to higher magnifications for a closer look.
When viewing a specimen under the microscope you should always start with the?
low power objective lens to locate and focus on the specimen before moving to higher magnifications.
Do you start with the lowest power lens on a microscope first?
Yes, it is best to start with the lowest power lens when using a microscope. This allows you to locate and focus on the specimen before moving to higher magnifications. Starting with a higher power lens can make it harder to locate and focus on the specimen.
What are the precautions to be taken while using a compound microscope?
When using a compound microscope, ensure that the microscope is placed on a stable, flat surface to prevent tipping. Always use the lowest power objective lens first to locate your specimen, and gradually switch to higher magnifications. Handle the slides carefully to avoid breakage, and clean the lenses with appropriate lens paper to prevent scratches. Finally, avoid touching the glass with your fingers to maintain clarity and prevent contamination.

What lens on a microscope are used to locate the specimen?
To locate a specimen on a microscope, the low power objective lens is typically used, often a 4x or 10x magnification. This lens provides a wider field of view, making it easier to scan the slide and find the specimen. Once located, higher power objective lenses can be used for more detailed observation.
Lens used to locate specimen on a microscope?
The lens used to locate a specimen on a microscope is typically the lowest magnification lens, known as the scanning lens or low power objective. This lens provides a wide field of view, making it easier to find and center the specimen before switching to higher magnification lenses for detailed viewing.
Describe briefly and systematise the manner of properly using a microscope?
To properly use a microscope, begin by placing the slide on the stage and securing it with stage clips. Start with the lowest power objective lens to locate the specimen, using the coarse focus knob to bring it into view. Once focused, switch to higher power lenses, using the fine focus knob for clarity. Always ensure to clean the lenses and cover the microscope when not in use to maintain its condition.
When beginning to focus should you use the lowest power lens of the microscope?
Yes, when starting to focus a microscope, it's best to use the lowest power lens. This allows for a wider field of view, making it easier to locate the specimen. Once the specimen is in focus at low power, you can then switch to higher power lenses for more detailed observation. This method also helps prevent damage to the slides or lenses.
Where should you be looking when you change objective lenses?
When changing objective lenses on a microscope, you should look at the specimen through the eyepiece rather than directly at the objective lenses. This allows you to ensure proper alignment and focus without risking damage to the slide or the lenses. It's also important to start with the lowest power objective to locate the specimen before switching to higher magnifications. Always handle the lenses carefully to avoid any misalignment or scratches.
What power lens should you start with on a microscope?
You should typically start with the lowest power lens (usually 4x or 10x) on a microscope to locate and focus on your specimen. This allows you to have a wider field of view and better control over the focusing before switching to higher power lenses for more magnification.
When using a compound light microscope and focusing should the lowest power lens should be used?
Yes, when using a compound light microscope, it is recommended to start with the lowest power lens (usually 4x or 10x) to locate and center the specimen before switching to higher magnifications. This helps in getting a broader view and making it easier to focus accurately at higher magnifications.
What observe lens should be used when you first look at a specimen under the microscope?
When first examining a specimen under a microscope, you should start with the lowest power objective lens, typically the 4x or 10x lens. This allows for a broader field of view, making it easier to locate the specimen. Once the specimen is in focus, you can then switch to higher power lenses for more detailed observation. Always ensure to adjust the stage and focus carefully to avoid damaging the slides or lenses.
How do you turn on a microscope?
To turn on a microscope, first ensure that it is plugged into a power source. Then locate the power switch, usually at the base of the microscope, and turn it on. Allow the microscope to power up fully before using it.
Do wasps have eyes and how do they use them to navigate their surroundings?
Yes, wasps have eyes. They use their compound eyes to detect movement, locate food, and navigate their surroundings. These eyes are made up of many tiny lenses, allowing them to see a wide field of view and detect fast movements.
