Exercise 76

Match the following types of microscopy with their descriptions:

____ Bright-field              1. Indirect light is reflected off the object

____ Phase              2. Objects split light into two beams

____ Polarized              3. Low refractive index objects may be overlooked

____ Dark-field              4. Three-dimensional images

____Fluorescent              5. Forms halo of light around object

____Interference              6. Detects electrons contrast emitted from objects

                         7. Detects specific wavelengths of light emitted from objects

Step 1 of 7

Bright filed microscopy:

• The amount of light are not controlled properly , which penetrate into the specimen

• Sediment constituents in high intensity light with “low refractive index is overlooked”

• Sediment is stained to elevate the visualization of the elements
