Light travelling through air encounters various phenomena, including interference, refraction, reflection, and diffraction. Diffraction occurs when light encounters an obstacle. The wavefront on the other side of a small opening is comparable in size to the wavelength λ  of the light passing through it. Observations of single slit diffraction can be made when light passes

Interference, in physics, is when two waves come together. It is a phenomenon in which when light waves move in a medium, there is a change or variation in the intensity of light of these waves. When two light waves of equal frequency travel in the same medium in the same direction, the intensity of

One of the fundamental concepts in optics is coherence, which is closely tied to light’s capacity to exhibit interference effects. When the electric field values at different locations or times have a constant phase connection, the light field is said to be coherent. Coherence, which is strongly linked to light’s ability to exhibit interference effects,

A fixed strong phase relationship between the differentiation regions of the beam profile is termed spatial coherence. The best-demonstrated example of the concept is a laser beam focused over a cross-section area. In this scenario, the beams of electricity act in different ways at different locations. The concept of spatial coherence is the basic principle

Introduction Binoculars and microscopes show a large image of an object to the eye. It is not necessary that the small compositions of the object should be clearly visible only because of the enlargement of the image. The resolving power of a telescope or microscope tells us how far apart points can be seen separately.

The Rayleigh criteria establishes the smallest distance between two light sources that can be resolved into separate objects. When a point source, such as a star, is examined using a circular aperture telescope, the image is a disc encircled by a number of very faint rings, rather than a point source. Fraunhofer diffraction of light

System response, and how quickly a signal can be transmitted or a document received, is what transmission quality means and is all about. Several things can have an impact on the transmission quality: the number of devices on the network  the transmission medium’s bandwidth network delay based on the type of traffic amount of mistakes

Coherence is a fixed relationship between the phase of waves in a single frequency beam of radiation. They are coherent when the phase difference between two light beams is consistent; they are noncoherent when the phase difference is random or fluctuating. Only coherent sources emit stable interference patterns, typically created by splitting a single beam
