Q.  
Which of the following are true for electron microscopy?


Answer & Explanation

For electron microscopy to work, the specimen must be thin and dry so electrons can pass through it. The image is obtained on a phosphorescent screen, and the electron beam must travel through an evacuated chamber to prevent scattering by air molecules. All these factors are essential for obtaining clear electron microscope images.

Thus correct option is: D.
