이 집합의 용어 (20)

  • What is the primary function of the compound microscope?
    To magnify small objects or specimens that are not visible to the naked eye using multiple lenses.
  • What are the two main lenses in a compound microscope?
    The objective lens and the eyepiece (ocular) lens.
  • What is the role of the objective lens in a compound microscope?
    To gather light from the specimen and create a magnified image.
  • What does the eyepiece lens do in a compound microscope?
    It further magnifies the image produced by the objective lens for viewing.
  • How does the compound microscope achieve high magnification?
    By combining the magnification powers of the objective and eyepiece lenses.
  • What is the function of the stage in a compound microscope?
    To hold and support the specimen slide in place.
  • What is the purpose of the diaphragm in a compound microscope?
    To control the amount of light reaching the specimen.
  • Why is the light source important in a compound microscope?
    It illuminates the specimen so details can be seen clearly.
  • What is the function of the coarse adjustment knob?
    To make large focus adjustments to bring the specimen into general focus.
  • What does the fine adjustment knob do?
    It makes small, precise focus adjustments for a sharp image.
  • Why is the compound microscope useful in biology?
    It allows observation of cells, microorganisms, and tissue structures.
  • How does the compound microscope differ from a simple microscope?
    It uses two or more lenses for greater magnification, while a simple microscope uses only one lens.
  • What is the typical magnification range of a compound microscope?
    Usually between 40x and 1000x magnification.
  • What is the function of the nosepiece in a compound microscope?
    To hold and rotate the objective lenses to change magnification.
  • How does the compound microscope improve resolution?
    By using multiple lenses and proper illumination to distinguish fine details.
  • What is the importance of cleaning lenses in a compound microscope?
    To ensure clear, sharp images without distortion or blurring.
  • What is the function of the body tube in a compound microscope?
    To maintain the correct distance between the eyepiece and objective lenses.
  • How does adjusting the diaphragm affect the image?
    It changes contrast and brightness by controlling light intensity.
  • What is the role of immersion oil in microscopy?
    To increase resolution by reducing light refraction between the slide and lens.
  • Why must specimens be thin when viewed under a compound microscope?
    To allow light to pass through for clear visualization of internal structures.
