Question

claim: images under the light microscope are reversed and inverted.
evidence: (draw out relevant tests or observations that can be performed or observed to support the claim.)

• sketch or list the steps taken.
• label or underline important parts of the microscope used during the investigation.

reasoning: (connect evidence to claim)
this happens because the lenses in the light microscope bend (refract) light, which flips the image both vertically and horizontally. as light passes through the curved lenses, it creates an image that is reversed and inverted, proving the claim true.

Explanation:

Evidence:

1. Steps:

• Place a small, printed letter (e.g., “e”) on a microscope - slide.
• Place the slide on the stage of the light microscope.
• Use the coarse - adjustment knob to focus on the letter at low power.
• Observe the orientation of the letter through the eyepiece.
• Switch to higher power if needed and refocus using the fine - adjustment knob while observing the letter's orientation.

1. Important parts of the microscope:

• Objective lenses: These are the lenses closest to the specimen and are responsible for magnification. They bend the light rays coming from the specimen.
• Eyepiece: The lens through which the observer looks. The image formed by the objective lenses is further magnified by the eyepiece.
• Stage: Holds the specimen (slide) in place.
• Coarse - adjustment knob: Used to make large adjustments to the focus when starting to view a specimen.
• Fine - adjustment knob: Used to make small, precise adjustments to the focus for a clear image.

Reasoning:

The lenses in the light microscope bend (refract) light. As light passes through the curved objective and eyepiece lenses, it creates an image that is both vertically and horizontally flipped. When observing a small letter like “e” on a slide, the orientation of the letter seen through the microscope is reversed and inverted compared to its actual orientation on the slide. This observation supports the claim that images under the light microscope are reversed and inverted.
