    What is the main goal of a laser?

  • transmit light signals over large distances from one point to another
  • display images onto screens or walls
  • control the way energized atoms release photons.
  • make distant objects visible
  • 2. 
    Which description best explains how fiber optics work?

  • The light in this instrument travels by travelling down a “hallway” and bouncing off through total internal reflection
  • light is passed through a prism where it is then put on a screen
  • This instrument works by exciting atoms and causing them to release photons. After the photons have been released, they bounce back and forth until they are emitted out of the device.
  • This instrument uses a laser that shines light into a lens. The lens then hits a splitter where it is split from one beam to two. The two beams of light then hit mirrors that direct them to their correct locations.

    Which description best matches how a camera works?

  • Light is gathered from a tiny area of a well-illuminated specimen close by. Then it is brought into focus by a lens.
  • Light hits a lens, bending it in one direction and a new direction as it leaves. It then converges together and creates a real image, where it is planted onto film through a chemical reaction.
  • White light travels through pixels, where it then passes through a prism and the 3 primary colors become dispersed so multiple colors are displayed.
  • Light is collected from distant objects and brought into focus. The eyepiece then takes the light and spreads it out in your field of vision.

    What are the main parts of holograms?

  • a laser, shutter, beam splitter, lenses, mirrors and film
  • lens, film, body
  • lens, dichroic prism, screen, colored light, regular mirror and dichroic mirror, light source (white light)
  • Objective lens (can be either mirrors or glass), eyepiece, aperture, pupil
  • 5. 
    What is the main goal of a fiber optic?

  • Make a chemical record of the pattern of light onto film.
  • make objects really small in size larger/visible
  • control the way energized atoms release photons
  • transmit light signals over large distances from one point to another.

    Which best matches the description of how an LCD projector works?

  • White light is sent through a prism that takes the 3 primary colors and disperses them so multiple colors are displayed.
  • The instrument excites atoms and causes them to release photons, which then bounce back and forth until they are emitted.
  • Light hits a splitter where it splits from 1 beam to two. The light then hits mirrors which sends them to correct locations, where they are recorded with film.
  • Light is gathered from a tiny area of a well-illuminated specimen close by. Then it is brought into focus by a lens.
  • 7. 
    What is the main goal of an LCD projector?

  • display images onto screens or walls
  • control the way energized atoms release photons.
  • make very distant objects visible
  • make a chemical record of the pattern of light onto film.
  • 8. 
    Which description best explains how telescopes work?

  • The instrument gives you a "bigger eye" by collecting light from distant objects and bringing it into focus.
  • white light gets changed by pixels, passes through a prism and is then dispersed.
  • light is gathered from a tiny area, which is then brought into focus and magnified by a lens.
  • a laser hits a splitter and then hits mirrors, creating a 3-dimensional image

    Which best matches the description of a microscope?

  • The instrument collects lots of light from distant objects and brings that light into focus, taking up more space in your field of vision.
  • light hits a lens and gets bent, creating a real image. the image is then planted onto film and leaves an impression by a chemical reaction
  • atoms are excited and release photons, which bounce back and forth until they are emitted out of the device.
