Principle of Superposition

Content Provider AK Lectures
Description The principle of superposition provides us with a way to combine two or more waves that are traveling together at some given region in space at the same moment in time. Recall that this combination is commonly referred to as wave interference and the wave that is produced is known as the composite wave. The principle of superposition states that in order to determine the displacement of the composite wave, we need to take the algebraic sum of the displacements of the individual waves. Note that even though we are combining waves, each wave acts independently of other waves and will resume its shape once the waves separate. Another important concept that stems of the superposition principle is known as Fourier's Theorem, which states that any complex or composite wave can be broken down into simple sinusoidal waves.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
