Reflexion Sentence Examples

The corollary, that the electric resistance of a metal can be determined in absolute units by experiments on the reflexion of heat-rays from its surface, is a striking illustration of the unification of the various branches of physical science, which has come in the train of the development of the theory of the aether.

In this event, the whiteness of the tips will be due to the scattering or irregular reflexion of the incident rays of light from the surface of the numerous gas bubbles.

But more widespread perhaps than any belief, from its simplicity doubtless, is the idea that the body's shadow or reflexion is the soul.

But, having ascertained by experiment that for all colours of light the angle of incidence is equal to the angle of reflexion, he turned his attention to the construction of reflecting telescopes.

These authors proved, however, that no optical system can justify these suppositions, since they are contradictory to the fundamental laws of reflexion and refraction.

In the former case the light penetrating between the particles is unable to escape by reflexion, and is finally absorbed.

The only cure appears to consist in breaking up the reflecting surfaces so that the reflexion shall be much less regular and distinct.

The limits of scientific cognition become intelligible, only when the sphere of understanding is subjected to critical reflexion and compared with the possible sphere of reason, that is, the sphere of rationally complete cognition.

It is a sad reflexion on what is supposed to be a National Health Service.

Reference should be made to the articles Reflexion, Refraction, and Caustic for the general characters of reflected and refracted rays (the article Lens considers in detail the properties of this instrument, and should also be consulted); in this article will be discussed the nature, varieties and modes of aberrations mainly from the practical point of view, i.e.

The effect is complicated, in the case of chlorophyll and many other bodies, by selective reflexion and fluorescence.

Alexius was evidently consoling himself with the reflexion that the future belonged to him.

This discovery was followed by that of the calculus of partial differences, the first trials of which were published in his Reflexion sur la cause generale des vents (1747).

Incipient Reflexion on the Story.-Let us give some instances of this.

Again, we may split a narrow beam of light by partial reflexion from a transparent plate, and recombine the constituent beams after they have traversed different circuits of nearly equivalent lengths, so as to obtain interference fringes.

They are sunk in a paganism which seems to embrace some faint reflexion of Greek mythology, Zoroastrian principles and the tenets of Buddhism, originally gathered, no doubt, from the varied elements of their mixed extraction.

The difficulty is that the automatic motion of a single mirror capable of reflecting the rays of any star continuously along the axis of a fixed horizontal telescope, requires a rather complex mechanism owing to the variation of the angle of reflexion with the diurnal motion.
