From January 2020 onwards, an additional Paper-III is being introduced for B.Planning courses separately. [4] Due to the COVID-19 pandemic in 2020, JEE-Main 2021 has a change in paper format and number of attempts. Now there will be 20 single choice questions and 10 numerical questions out of which only five numerical questions are to be attempted.
The Joint Entrance Examination – Advanced (JEE-Advanced) (formerly the Indian Institute of Technology – Joint Entrance Examination (IIT-JEE)) is an academic examination held annually in India that tests the skills and knowledge of the applicants in physics, chemistry and mathematics.
The exam has 60 multiple-choice questions (48 single-correct and 12 multi-correct), with a 2-hour time limit. It's held on the last Sunday of November, and the top 400 students (200 each, group A & group B) advance to the Indian National Physics Olympiad (INPHO). The syllabus aligns broadly with up to CBSE Standard 12 Physics.
The narrow-width limit of the Gaussian wave packet solution discussed is the free propagator kernel K. For other differential equations, this is usually called the Green's function, [22] but in quantum mechanics it is traditional to reserve the name Green's function for the time Fourier transform of K.
The interference of two waves. In phase: the two lower waves combine (left panel), resulting in a wave of added amplitude (constructive interference). Out of phase: (here by 180 degrees), the two lower waves combine (right panel), resulting in a wave of zero amplitude (destructive interference). Interfering water waves on the surface of a lake
Shallow-water equations can be used to model Rossby and Kelvin waves in the atmosphere, rivers, lakes and oceans as well as gravity waves in a smaller domain (e.g. surface waves in a bath). In order for shallow-water equations to be valid, the wavelength of the phenomenon they are supposed to model has to be much larger than the depth of the ...
Partial-wave analysis, in the context of quantum mechanics, refers to a technique for solving scattering problems by decomposing each wave into its constituent angular-momentum components and solving using boundary conditions.
Mechanical waves can be produced only in media which possess elasticity and inertia. There are three types of mechanical waves: transverse waves, longitudinal waves, and surface waves. Some of the most common examples of mechanical waves are water waves, sound waves, and seismic waves. Like all waves, mechanical waves transport energy.
