Light Microscope Mastery

What is the function of the eyepiece in a light microscope?

• To magnify the image

• To illuminate the specimen

• To adjust the focus

• To hold the microscope steady

Explain the proper way to carry a light microscope from one location to another.

• Hold the microscope with just one finger

• Use both hands to hold the microscope firmly, with one hand under the base and the other hand supporting the arm.

• Use one hand to carry the microscope by the lens

• Carry the microscope upside down

How can you adjust the light intensity on a light microscope?

• By pressing the power button

• By using the diaphragm or iris control

• By changing the objective lens

• By adjusting the focus knob

Describe the steps to focus under high power on a light microscope.

• Switch to the low power objective lens and use the coarse adjustment knob

• Use the fine adjustment knob first, then switch to the high power objective lens

• Adjust the focus using the high power adjustment knob

• Adjust the focus using the coarse adjustment knob, then switch to the high power objective lens and use the fine adjustment knob to further focus the specimen.

What are the necessary steps to prepare a slide for viewing under a light microscope?

• Adjusting the focus and light intensity before placing the specimen on a slide

• Adding a cover slip and then removing the specimen from the slide

• Placing the specimen on a slide and shaking it vigorously

• Placing the specimen on a slide, adding a cover slip, and adjusting the focus and light intensity

Why is it important to clean the lenses of a light microscope after use?

• To remove residue or debris that may affect future observations.

• To prevent the microscope from getting scratched

• To make the microscope look cleaner

• To save time by not having to clean it later

What should be done if the light microscope is not in use for an extended period of time?

• Store it in direct sunlight

• Cover it with a dust cover and store it in a clean, dry place.

• Leave it uncovered in a humid environment

• Spray it with water and leave it to air dry

Explain the proper way to store a light microscope when not in use.

• Leave it uncovered and exposed to dust

• Store it in a damp and humid environment

• Place it upside down on a dirty surface

• Cover it with a dust cover or a clean cloth

What are the consequences of using the coarse adjustment knob under high power?

• Enhanced durability of the objective lens

• Potential damage to the objective lens and slide

• Improved clarity and focus of the specimen

• Better resolution and magnification of the image

Why is it important to handle the light microscope with care and attention?

• To see if it can withstand rough handling

• To prevent damage and ensure accurate results

• To test its durability by dropping it

• To use it as a toy
