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.
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.
Sinusoidal plane-wave solutions are particular solutions to the wave equation. The general solution of the electromagnetic wave equation in homogeneous, linear, time-independent media can be written as a linear superposition of plane-waves of different frequencies and polarizations .
Shortest path (A, C, E, D, F), blue, between vertices A and F in the weighted directed graph. In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized.
Capillary waves (ripples) in water Ripples on Lifjord in Øksnes Municipality, Norway Capillary waves produced by droplet impacts on the interface between water and air.. A capillary wave is a wave traveling along the phase boundary of a fluid, whose dynamics and phase velocity are dominated by the effects of surface tension.
