Davidson and Germer experiment

This experiment is done by two scientists in which electrons are scattered by the surface of a crystal made of nickel metal and later it displayed diffraction patterns. This experiment of them also gives a green signal to the experiment done by de Broglie mentioning of wave-particle duality and which later become the millstone in … Read more

Single Slit Diffraction

Diffraction Due to ASingle Slit, Width of Central Maximum The single slit diffraction can be observed when the light is passing through the single slit, which is having a width in the order of light’s wavelength. On the screen, the diffraction pattern will be at a distance L away from the slit. Here the intensity … Read more

Interference Young’s Double Slit Experiment

Interference Young’s Double Slit Experiment and Expression for Fringe Width, Coherent Sources and Sustained Interference of Light The observation of the interference effect is an indication of the presence of overlapping waves. It was postulated by Thomas Young that light is having the wave-like properties and it is subjected to the superposition principle. His experiment … Read more

Proof of laws of reflection and refraction

The Huygens’s principle is based on the imagination that each point of the propagating disturbances is capable to originate the new pulses, which are also contributing to the disturbances at the later instances. The laws of geometrical optics can be implied to show his model of light propagation. This law states that all the points … Read more

Huygens’s Principle

Wave Optics: WaveFront and Huygens’s Principle, Reflection and Refraction of Plane Wave at APlane Surface Using Wave Fronts According to the Huygens’s principle, all points on a wavefront can be regarded as sources of secondary wavelets that are spherical in nature, and their direction of spreading is forward, just like the speed of light. The … Read more

Microscopes and Astronomical Telescopes

Microscopes and Astronomical Telescopes (Reflecting and Refracting) and their Magnifying Powers The telescope is an optical instrument that is having two optical elements, an eyepiece, and an object. Each of the optical telescopes will be in one of the categories of reflecting or refracting. This classification is based on the method, that is used for … Read more

Refraction and Dispersion of Light Through A Prism

The prism is glass or any transparent material in the prism form that is triangular with the refracting surfaces at the acute angle, with one another and causes the separation of light into a spectrum of colors. Refraction Through Prism The light rays suffer two refractions when they are passing through the prism, and they … Read more

Scattering of the Light

Scattering of the Light – Blue Color of the Sky and Reddish Appearance of the Sun at Sunrise and Sunset When the energy waves such as sound light or the electromagnetic waves are made to depart from the straight path due to imperfections, or irregularities in the medium, then it is known as scattering. Scattering … Read more

Power of A Lens

Magnification, Power of ALens, Combination of Thin Lenses in Contact Combination of ALens and AMirror Magnification of the lenses is defined as the ratio of the height of the image to the ratio of the height of the object. It can also be defined in terms of distance of image and object. Power of Lens … Read more

Brewster’s Law

Polarization, Plane PolarizedLight Brewster’s Law, Uses of Plane PolarizedLight and Polaroids Polarizing is the transformation of unpolarized light to the polarized light. In the unpolarized light, the particles are vibrating in the different planes. The unpolarized light can be polarized by the use of polaroid, scattering and refraction and reflection. The scattered light that is … Read more
