Why there are dark and bright fringes on the screen of ripple tank?
123
Why does dull dark objects emit more heat than bright shiny ones?

What color is not bright?
In my opinion black isn't a bright color, but if you don't consider black a color then any color with the word dark in front of it is usually not bright. The color brown isn't very bright either but essentially any color can be bright in the eyes of the beholder.

What is Dark field microscopy?
Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.

How is spirochete activity seen?
observation with dark-field microscopy .
Why use fluorescence microscopy for bacillus anthracis?
Perhaps fluorescence would be used because B. athracis has a cell wall making it difficult to visualize the details of the cytoplasm by simple bright field microscopy. Flourescence allows for labeling of specific entities, and "cold" illunimation of those entities against a dark field.
What is darkfield microscopy?
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'

How is diagnosis for yaws conducted?
using a technique called dark-field microscopy. This often allows the spirochetes to be identified. They may also be identified in fluid withdrawn from swollen lymph nodes
