NettetThe classical example of discrete spectrum (for which the term was first used) is the characteristic set of discrete spectral lines seen in the emission spectrum and absorption spectrum of isolated atoms of a chemical element, which only absorb and emit light at particular wavelengths. The technique of spectroscopy is based on this phenomenon. NettetThe displacement is given by finding the area under the line in the velocity vs. time graph. The acceleration is given by finding the slope of the velocity graph. The instantaneous velocity can just be read off of the graph. To find the average velocity, recall that v avg = Δ d Δ t = d f − d 0 t f − t 0 Discussion kedarnath comes in which district

NettetCurved lines have changing slope; they may start with a very small slope and begin curving sharply (either upwards or downwards) towards a large slope. In either case, the curved line of changing slope is a sign of accelerated motion (i.e., changing velocity). NettetIn atomic physics, the Rydberg formula calculates the wavelengths of a spectral line in many chemical elements. The formula was primarily presented as a generalization of the Balmer series for all atomic electron transitions of hydrogen. NettetThe answer is that they are ordinarily motionless relative to the Earth. Furthermore, their acceleration is zero because they remain motionless. That means they also have something in common with a car moving at a constant velocity, because anything with a constant velocity also has an acceleration of zero. lazy boy top grain leather sofa
