Wavelength interference results in small observed objects (like bacteria) being surrounded by:
A) a capsule
B) a membrane
C) an Airy disk
D) a dark field
E) a cell wall

Question

Quizplus · Accepted Answer

Wavelength interference results in the formation of an Airy disk around small observed objects like bacteria. The Airy disk is a result of the diffraction of light around the object, and it is a characteristic feature of high-resolution microscopy techniques like confocal microscopy and fluorescence microscopy. The Airy disk is a bright central spot surrounded by a series of concentric rings, which represent the interference patterns of diffracted light waves.
