When the two waves are in phase, i. e. the path difference is equal to an integral number of wavelengths, the summed amplitude, and therefore the summed intensity is maximum, and when they are in anti-phase, i. e. the path difference is equal to half a wavelength, one and a half wavelengths, etc., then the two waves cancel and the summed intensity is zero.

When integrated along all possible paths, with a phase factor which is proportional to the path length, the interference of the wave-functions correctly predicts observable phenomena.

When a body at these points is perturbed, it moves away from the point, but the factor opposite of that which is increased or decreased by the perturbation ( either gravity or angular momentum-induced speed ) will also increase or decrease, bending the object's path into a stable, kidney-bean-shaped orbit around the point ( as seen in the rotating frame of reference ).

* When you jump, it is usually bad to leave an easily used return path for your opponent to " undo " your progress.

When the Sun's path crosses the equator, the length of the nights at latitudes + L ° and-L ° are of equal length.

When the shutter is released, the mirror moves out of the light path, and the light shines directly onto the film ( or in the case of a DSLR, the CCD or CMOS imaging sensor ).

When the plastic is cool, the carbon grains are all in contact with each other, forming a conductive path through the device.

When we follow the path, we get the result, which is nirvana.

When people hear that they should follow the path, they might think that a ready-make system exists, and that individual expressions are not required.

When the DS3 enters a SONET network, path overhead is added, and that SONET network element ( NE ) is said to be a path generator and terminator.

When an interruption in a network topology occurs, the software running on the networking electronics calculates another route to the desired destination via an alternate available path.

When the FM improvement factor is greater than unity, the improvement in the SNR is always obtained at the expense of an increased bandwidth in the receiver and the transmission path.

When an object moves from one location to another, the force changes the potential energy of the object by an amount that does not depend on the path taken.

When understood in this way, it is clear how the algorithm necessarily finds the shortest path, however it may also reveal one of the algorithm's weaknesses: its relative slowness in some topologies.

When it was to be constructed, the engineers proposed to Nicholas that he draw the path of the future railroad on the map himself.

When one attempts to solve problems in this class, it makes no difference whether ZF or ZFC is employed if the only question is the existence of a proof.

When one manuscript has a difference compared to 99 % of the others, it is understood to be a copyist's mistake.

" When his wife reported to him that his interpreter's wife had boasted of her own husband's greatness, R. Abbahu simply said, " What difference does it make which of us is really the greater, so long as through both of us heaven is glorified?

When the star is a distant object, parallax is negligible and the difference is due mostly to aberration.

When g ( x ) equals g ( a ), then the difference quotient for is zero because f ( g ( x )) equals f ( g ( a )), and the above product is zero because it equals f ′( g ( a )) times zero.

When the angle θ does not satisfy the above condition, the horizontal component of force exerted by the road does not provide the correct centripetal force, and an additional frictional force tangential to the road surface is called upon to provide the difference.

When an electron in an excited molecule or atom descends to a lower energy level, it emits a photon of light equal to the energy difference.

When calculating the difference in voltage, one must first manipulate the half-cell reactions to obtain a balanced oxidation-reduction equation.

When the energy difference between the atomic orbitals of two atoms is quite large, one atom's orbitals contribute almost entirely to the bonding orbitals, and the others atom ’ s orbitals contribute almost entirely to the antibonding orbitals.

When you ’ re racing with the same boat, same engine, and same performance – the only difference between winning and losing is you.

When that happens, the phase difference determines whether they reinforce or weaken each other.

When the intensities are different, the result is a colorized hue, more or less saturated depending on the difference of the strongest and weakest of the intensities of the primary colors employed.

When ( modern ) Klingon Worf and his crewmates see an original-series Klingon, his crewmates ask about the stunning difference in appearance ; Worf says tersely that the matter is something Klingons " do not discuss with outsiders ".

When a conducting tip is brought very near to the surface to be examined, a bias ( voltage difference ) applied between the two can allow electrons to tunnel through the vacuum between them.

When the transmission detects a speed difference of greater than 20 % between the front and rear axle sets, the transmission progressively sends power to the rear wheels.

When the two signals are mixed, a " beat " frequency equal to the difference between the two frequencies is created.

When the actual transmitted ( incident ) power and the reflected power are known ( i. e., through measurements and / or calculations ), then the return loss in dB can be calculated as the difference between the incident power P < sub > i </ sub > ( in dBm ) and the reflected power P < sub > r </ sub > ( in dBm ),

When wage costs are applied to this difference ( the 8, 000 hours ) it becomes possible to financially value human capital risk within an organizational perspective.

When a voltmeter is connected between two different types of metal, it measures not the electric potential difference, but instead the potential difference corrected for the different atomic environments.

When an electrical potential difference ( a voltage ) is applied across the metal, the resulting electric field causes electrons to move from one end of the conductor to the other.
