Which two parts of the microscope are used to move the objective lens?
The coarse adjustment knob and the fine adjustment knob are used to move the objective lens up and down to focus on the specimen.
Where the image move in the microscope left or right?
In a compound microscope, the image moves in the opposite direction to the movement of the stage. So, if you move the stage to the right, the image will appear to move to the left, and vice versa. This is due to the optics of the microscope, where the image is flipped by the objective lens.
Why should you always move the objective lens away from the slide when your focusing the microscope?
Moving the objective lens away from the slide when focusing prevents the lens from accidentally coming into contact with the slide and potentially damaging both the lens and the specimen. It also helps in preventing the lens from scratching the slide, ensuring clear and accurate observations.
What happens to the microscope image when you move the microscope slide towards you?
The image will move upwards in the field of view when the slide is moved towards you. This is because the slide is physically closer to the objective lens, resulting in the object on the slide appearing to move in the opposite direction.
How is the low power objectives lens manipulated to focus a specimen for observations under a light microscope?
The low power objective lens in a light microscope is manipulated by rotating the nosepiece to engage the correct lens. Then, use the coarse focus knob to move the objective lens close to the specimen until it is in focus. Finally, use the fine focus knob to fine-tune the focus for a clear view of the specimen.

What is the lens that is closest to the eye in a light microscope?
On a microscope with the usual 3-lens turret it is usual to use the objective lens with the lowest magnification to first examine your specimen. This gives a wider overall view of the subject, and will allow you to choose the particular detail that best suits your study. You may then move on to a higher magnification, if necessary, to study finer detail. If you started with the highest magnification, your fine focus will be uncertain, and you risk the front of the objective lens coming into contact with the sample slide. This could damage your specimen, and may damage the front of the lens.
What objective brings a specimen into focus using a microscope?
The objective lens of a microscope brings a specimen into focus by adjusting the distance between the lens and the specimen. This is done by turning the focus knob to move the lens up or down, which changes the focal point and sharpens the image.
What do the stage controls do on a microscope?
The stage controls on a microscope are used to move the specimen slide horizontally or vertically to adjust its position relative to the objective lens. This allows you to focus on different areas of the specimen and also to scan across it to observe different parts.

What is the function of the stage control of a microscope?
The stage control of a microscope is used to move the specimen being observed on the stage. It allows for precise positioning and focusing of the specimen under the objective lens for observation and analysis. By adjusting the stage, different parts of the specimen can be brought into view for detailed examination.
What happens when you move a microscope slide to the right?
When you move a microscope slide to the right, the field of view under the objective lens shifts in the opposite direction, appearing to move to the left in the eyepiece. This movement helps you navigate the sample and focus on different areas for observation.
Explain how focussing occurs in a microscope?
Focusing in a microscope is achieved by adjusting the distance between the objective lens and the specimen. By moving the lens closer or farther away from the specimen, the light rays passing through the lens converge or diverge, resulting in a sharp image. The fine focus knob is used for precise adjustments to achieve a clear and crisp image of the specimen.
What happens when you move the slide up and down in a microscope?
When you move the slide up and down in a microscope, it changes the focal distance between the objective lens and the specimen on the slide. This helps to bring different parts of the specimen into focus for observation and analysis. Additionally, it allows you to navigate through different layers of the specimen to examine various features in more detail.
