For Euclid ’ s method to succeed, the starting lengths must satisfy two requirements: ( i ) the lengths must not be 0, AND ( ii ) the subtraction must be “ proper ”, a test must guarantee that the smaller of the two numbers is subtracted from the larger ( alternately, the two can be equal so their subtraction yields 0 ).

The red dot overtakes two green dots when moving from the left to the right of the figure. New waves seem to emerge at the back of a wave group, grow in amplitude until they are at the center of the group, and vanish at the wave group front. For surface gravity waves, the water particle velocities are much smaller than the phase velocity, in most cases.

For the cooler stars, dwarfs such as red dwarfs, orange dwarfs, and yellow dwarfs are indeed much smaller and dimmer than other stars of those colors.
For example, white dwarfs are a different kind of star that is much smaller than main-sequence stars — being roughly the size of the Earth.
For example, a road map may not show railroads, smaller waterways or other prominent non-road objects, and even if it does, it may show them less clearly ( e. g. dashed or dotted lines / outlines ) than the main roads.
For the same reason, larger nuclei ( more than about eight nucleons in diameter ) are less tightly bound per unit mass than are smaller nuclei ; breaking a large nucleus into two or more intermediate-sized nuclei, releases energy.
For point masses the gravitational energy decreases without limit as they approach zero separation, and it is convenient and conventional to take the potential energy as zero when they are an infinite distance apart, and then negative ( since it decreases from zero ) for smaller finite distances.

For and photon
For example, if a single photon strikes the electrons, only a single electron changes states in response to the photon.
For instance, each photon that travels through intergalactic space loses energy due to the redshift effect.
For commonly used fluorescent compounds, typical excited state decay times for photon emissions with energies from the UV to near infrared are within the range of 0. 5 to 20 nanoseconds.
For high energy gamma, this relies on interaction of the photon radiation with the tube wall material, usually 1-2mm of chrome steel to produce electrons which can enter and ionise the fill gas.
For example, a single photon may be refracted by a lens or exhibit wave interference with itself, but also act as a particle giving a definite result when its position is measured.

For example, in most string theories one of the closed string modes is the graviton, and one of the open string modes is the photon.
For electromagnetic radiation, the amplitude of a photon corresponds to the changes in the electric field of the wave.
For example, for the probability that a photon will reflect off of a mirror and be observed at a given point a given amount of time later, one sets the photon's probability amplitude spinning as it leaves the source, follows it to the mirror, and then to its final point, even for paths that do not involve bouncing off of the mirror at equal angles.
For a photon, its momentum, and thus can be substituted for for all photon momentum terms which arise in course of the derivation below.
For the spontaneous Raman effect, which is a form of light scattering, a photon excites the molecule from the ground state to a virtual energy state.
For example, if a photon in a plus spin state has a 0. 1 amplitude to be absorbed and take an atom to the second energy level, and if the photon in a minus spin state has a − 0. 1 amplitude to do the same, a photon which has an equal amplitude to be plus or minus would have zero amplitude to take the atom to the second excited state and the atom will not be excited.
For example, the pattern ( probability distribution ) produced by millions of photons passing through a diffraction slit can be calculated using quantum mechanics, but the exact path of each photon cannot be predicted by any known method.
