Prism formula

Prism A prism is a polyhedron having five sides and a triangular cross-section. There are two identical parallel triangles opposite each other in a prism. Three rectangular surfaces are also inclined to each other, in addition to the triangles. Prisms are translucent solids that are used to refract light. The refracting surfaces are the two

Optical Fibre Uses

What is an optical fibre? Optical fibre is a type of data transmission technology that works by sending light pulses down a long fibre, which is usually made of plastic or glass. For optical fibre communication transmission, metal cables are chosen because signals move more safely. Optical fibres are unaffected by electromagnetic interference. The fibre

Matter waves-wave nature of particle

The dual nature of radiation and matter tells that every object has two natures associated with it i.e,  a wave and particle. It is most commonly known as wave-particle duality. The wave nature of particles came from Maxwell’s equations of electromagnetism and the experiment of generation and detection of electromagnetic waves done by Hertz. J.

Laws of refraction using Huygens principle

Dutch physicist Christiaan Huygens and French physicist Augustine-Jean Fresnel proposed the Huygens-Fresnel Principle, or simply Huygens Principle. Huygens’s principle explains methods of analysing problems related to wave propagation in the Far-field limit and Near-field diffraction and reflection. It states that every point of the wavefront is the source of spherical wavelets created in the process.

Laws of reflection using Huygens principle

What stream to choose after 10th? Reflection The rapid change in the propagation direction of a wave that reaches the boundary between two mediums is known as reflection. At least a portion of the approaching wave disturbance is contained within the same medium.  Types of Reflection The different types of reflection are as follows: Regular

Laws of Reflection

Reflection is derived from the Latin word reflectere, re: “back,” and flectere: “to bend,” so it means bending something back. Unless and until any obstacle or second medium arrives in the path of the light ray, the light travels in a straight line.  Law of Reflection  The reflection of light by a smooth surface is

Dispersion of Light By A Prism

Introduction Refraction is a natural phenomenon of bending light from one medium to another. The refraction occurs because of the change of speed of wave light on entering into another medium. This refraction is the cause of various other physical phenomena such as dispersion.  A prism is a well-polished optical element that is made to
