### Question 5
# Brief Explanations:
When a light microscope inverts and reverses an image, it means the image is flipped both vertically (inverted) and horizontally (reversed). For example, if an object is facing right, its image will face left, and if it's at the top of the specimen, it will appear at the bottom in the view. This is due to the way light passes through the microscope's lenses (objective and ocular), which use convex lenses to form the image, resulting in this orientation change.
# Answer:
It means the image is flipped vertically (inverted) and horizontally (reversed); e.g., a right - facing object appears left - facing, and a top - positioned object appears at the bottom in the view, due to lens - based image formation.

### Question 6
# Brief Explanations:
The field of view (the area visible through the microscope) is larger at low power. When moving to higher power, the field of view becomes smaller. If the image is not centered at low power, when we switch to higher power, the part of the specimen we want to observe may move out of the now - smaller field of view. Also, the stage adjustment range for centering at higher power is very small (since the objective is closer to the specimen), so centering at low power (with a larger field of view and more forgiving stage movement) ensures the object stays in view at higher power.
# Answer:
At low power, the field of view is large. When moving to higher power, the field of view shrinks. If not centered at low power, the object may move out of the smaller high - power field of view. Also, high - power stage adjustment is less forgiving, so centering at low power ensures the object remains visible.

### Question 7
# Brief Explanations:
- **Field of View**: The field of view is the area that can be seen through the microscope. When going from high - power to low - power objectives, the magnification decreases. A lower magnification means we can see a larger area of the specimen. So the field of view increases (becomes larger) when switching from high to low power.
- **Available Light**: The amount of light is related to the size of the objective's aperture (numerical aperture) and the field of view. Low - power objectives usually have a larger field of view and may allow more light to enter (or the light is spread over a larger area, making the overall available light per unit area seem like there is more, or the diaphragm/condenser settings that are set for low power can also affect it). In general, when going from high to low power, the amount of available light increases (the view becomes brighter) because the light is spread over a larger area, and also low - power objectives may have a larger aperture to let in more light.
# Answer:
- Field of View: Increases (becomes larger) as lower magnification at low power shows a bigger area of the specimen.
- Available Light: Increases (view becomes brighter) as light is spread over a larger area and low - power objectives may let in more light.

### Question 8
# Brief Explanations:
- **Magnification**: It is the process of making an object appear larger than its actual size. It is calculated as the product of the magnification of the objective lens and the ocular lens (e.g., a 10x objective and a 10x ocular give 100x magnification). It just relates to how big the image is compared to the real object.
- **Resolving Power (Resolution)**: It is the ability of a microscope to distinguish between two closely spaced objects as separate entities. It is determined by factors like the wavelength of light (for light microscopes) and the numerical aperture of the lenses. A higher resolving power means we can see finer details and separate objects that are very close together. So magnification is about how big the image is, while resolving power is about how well we can see fine details and separate objects.
# Answer:
- Magnification: Makes an object appear larger (product of objective and ocular magnifications), related to image size.
- Resolving Power: Ability to distinguish two close objects as separate, related to detail visibility.

### Question 9
# Brief Explanations:
Microscope lenses are very delicate and have special coatings. Facial tissue, T - shirts, or other materials can scratch the lens surface or leave behind fibers, dust, or chemicals. Lens tissue is designed to be soft and non - abrasive, and lens cleaner is formulated to clean the lens without damaging the coating or the lens itself. Using improper materials can damage the lens, reducing its ability to form clear images and potentially ruining the lens over time.
# Answer:
Improper materials (facial tissue, T - shirt, etc.) can scratch the lens, leave debris/chemicals, or damage lens coatings. Lens tissue is soft/non - abrasive, and lens cleaner is safe for the lens, preserving its imaging ability.
