Interference and diffraction

Width of central maximum

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 […]

Why Coherent Sources are Essential for Observable Interference

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

Temporal Coherence

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,

Spatial Coherence

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

Resolving power of microscopes

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.

Rayleigh Criterion

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

Quality of Transmission

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

Methods of Producing Coherent Source

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

Heisenberg’s γ-ray Microscope

Heisenberg’s γ-ray Microscope is a very high-resolution microscope that uses high-energy gamma rays for illumination. However, this microscope does not exist at present, but Heisenberg imagined it could see and locate the position of an electron with great accuracy. This high-resolution microscope uses high-energy light, giving the electron a bigger kick. According to the uncertainty

Height And Distance In Trigonometry

Trigonometry is a branch of science or mathematics that deals with calculating the heights, distances, or angles of any triangle. It also helps understand the relationship between the heights and distance in a triangle. Trigonometry was first introduced in astronomy, and then it gained great importance in all other fields such as geography and navigation.
