While looking through a light microscope, you slide the specimen to the left. Which way does the image appear to move?
ATo the left
BStraight down
CIt stays put
DTo the right
Answer & Solution
Correct answer: D. To the right
1. A microscope's two sets of lenses produce an inverted image.
2. A specimen that is right-side up appears upside-down, and motions reverse the same way.
3. If the slide is moved left, the image appears to move right.
4. Moving the slide down would make the image seem to move up, so directions flip rather than stay put.
5. Expecting the image to follow the slide to the left is the intuitive trap the lens system defeats.
