Question

use the following information to answer question 27.

a student decides to take apart an optical device to learn more about how it works. the students observations are listed below.

observations

• a mirror focuses the image.
• the only lens is in the eyepiece.
• a mirror redirects the image towards the eyepiece.
• the image is upside-down and mirrored left-to-right.

1. the optical device the student was using was a

a. telescope.
b. microscope.
c. set of binoculars.
d. set of eyeglasses.

use the following information to answer question 28.

recent technologies have emerged to enhance human vision. different technologies may affect particular regions of the eye.

1. which of the following technologies would be used to enhance the cornea of the eye?

a. laser eye surgery
b. colorblind glasses
c. night vision goggles
d. glare-blocking sunglasses

Analyze the optical device observations

The observations for Question 27 state:

• A mirror focuses the image (this indicates a reflecting system, such as a curved primary mirror).
• The only lens is in the eyepiece.
• A mirror redirects the image towards the eyepiece (characteristic of a Newtonian reflecting telescope design using a flat secondary mirror).
• The image is upside-down and mirrored left-to-right (typical of astronomical telescopes).

Among the options (telescope, microscope, binoculars, eyeglasses), a reflecting telescope fits all these criteria perfectly.

Identify the technology enhancing the cornea

Question 28 asks which technology is used to enhance or reshape the cornea of the eye.

• The cornea is the clear, protective outer layer of the eye that helps focus incoming light.
• Laser eye surgery (such as LASIK) works by using a laser to precisely reshape the cornea to correct refractive errors like nearsightedness, farsightedness, and astigmatism.
• Colorblind glasses affect light wavelengths reaching the retina.
• Night vision goggles and glare-blocking sunglasses do not alter or enhance the physical structure of the cornea itself.

Therefore, laser eye surgery is the correct technology.
