Study Notes
Microscopy
- A microscope uses sunlight or artificial light as its source of illumination.
- There are two types of microscopes: light microscope (مجهر املجال املشرق) and dark microscope (مجهر املجال املظلم).
Limitations of High Magnification
- At high magnification, the refraction of light can cause image distortion.
Components of a Microscope
- The condenser (مكثف) collects and focuses light from the illuminator onto the specimen.
- The condenser is located beneath the stage.
- The objective lens (عدسة موضوعية) is used to adjust the dioptric power.
Other Components
- The nosepiece (قطعة انف) is another component of a microscope.
- The stage (رأس) has controls for adjusting the microscope.
This quiz is about the basics of microscopy in biology, covering types of microscopes and their uses.
