1. Give the functios/uses of the following parts of the microscope.

a. Revolving Nosepiece
b. Coarse adjustment knob
c. Condenser
d. Stage
e. Mirror

a. Revolving Nosepiece: The revolving nosepiece, also known as the turret, is the part of the microscope that holds the objective lenses. It allows for easy and swift switching between different magnification levels without the need to manually remove and replace lenses.

b. Coarse adjustment knob: The coarse adjustment knob is used to bring the specimen into approximate focus. It moves the stage up and down, allowing for larger adjustments in focus. This knob is typically used only when starting to observe a specimen or when switching to a higher magnification objective.

c. Condenser: The condenser is a lens system located below the stage. Its primary function is to focus and direct light onto the specimen, making it more visible. It helps improve the illumination and clarity of the image by maximizing the amount of light that passes through the specimen.

d. Stage: The stage is the platform on which the specimen is placed for observation. It is equipped with clips or mechanical holders to secure the slide in place. The stage can be moved vertically using the coarse and fine adjustment knobs to bring the specimen into focus. It may also have controls to move the slide horizontally for precise positioning.

e. Mirror: The mirror is a reflective surface located below the stage. It serves as the light source for the microscope when using natural or ambient light. Its purpose is to reflect light upwards through the condenser and onto the specimen, providing the necessary illumination for observation. The mirror can be adjusted to control the angle and intensity of the light.

1. Functions/Uses of Microscope Parts:

- a. Revolving Nosepiece:
- Holds multiple objective lenses and allows the user to switch between different magnifications by rotating the nosepiece to align the desired lens with the specimen.

- b. Coarse Adjustment Knob:
- Used for bringing the specimen into general focus by moving the stage up and down quickly. It's used first, before fine tuning with the fine adjustment knob.

- c. Condenser:
- Focuses and concentrates the light onto the specimen, improving the clarity and contrast of the image seen through the lenses.

- d. Stage:
- A platform where the slide holding the specimen is placed. It usually has clips to hold the slide in place and can have mechanical controls to move the slide precisely.

- e. Mirror (or Light Source in modern microscopes):
- Reflects light from an external source up through the bottom of the stage to illuminate the specimen. In microscopes with built-in illumination, the mirror is replaced by a lamp.
