Interference And Differaction

[HNM]

How in microscope there is a phenomena of differaction, and in case of telescope there is interference of light happens ?

Diffraction and interference are related concepts, and you have both in both tools (and everywhere else where light is propagating).
I am not sure what exactly you are asking.

The normal terminology for the limit of resolution of a telescope is 'diffraction limit'. I wonder whether you are bringing in the idea of interference in the context of multiple telescope arrays.

'Everything' is diffraction, when you get down to it. Interference is a simple example of diffraction where a finite number of small coherent sources are involved. The Maths involved is usually somewhat simpler when you can treat a problem in terms of interference as you are Summing a small number of discrete sources rather than Integrating over a continuous aperture, when analysing diffraction.

The phenomena of diffraction and interference are both important principles in the field of optics, which is the study of light and its behavior. In a microscope, diffraction occurs when light passes through a small opening or aperture, such as the lens of the microscope. This causes the light waves to spread out and interfere with each other, creating a pattern of light and dark areas. This diffraction pattern can affect the image produced by the microscope, making it appear blurry or distorted.

On the other hand, in a telescope, interference occurs when light waves from different sources combine and interact with each other. This can happen when light passes through multiple lenses or mirrors in the telescope. The result is a complex interference pattern that can affect the quality of the image produced by the telescope.

The reason for the difference in the phenomena observed in microscopes and telescopes is due to the different designs and purposes of these optical instruments. Microscopes are designed to magnify small objects, such as cells or microorganisms, and therefore require a high level of precision in their optics. This precision can be affected by the diffraction of light passing through small openings in the microscope's lenses.

On the other hand, telescopes are designed to collect and focus light from distant objects, such as stars and galaxies. The interference of light waves in telescopes can cause distortions in the image, but this can be corrected through careful alignment and calibration of the telescope's optics.

In conclusion, the phenomena of diffraction and interference play important roles in the functioning of microscopes and telescopes. Understanding these principles is crucial for scientists and researchers who use these instruments in their work.
