... s ultra-violet rays than the light of the sun. This specific destructive action on the eye of short ultra-violet radiation extends beyond the blank space in the spectrum of radiation (Fig. 14) and still exists, though possibly to a lesser extent, in the X-rays. PHYSIOLOGICAL EFFECTS OF RADIATION. 57 Pathological and Therapeutic Effects of Radiation. 29. Radiation impinging on the tissue of the human body or other living organisms exerts an influence depending on intensity, power and frequency.

... . These ultra-violet radiations carry us up to frequencies of about 3000 X 1012 cycles per sec., or to wave lengths of about 10 X 10~6 cm. Then, however, follows a wide gap, between the highest frequencies of ultra-violet radiation and the frequencies of X-rays. In this gap, radiations of very interesting properties may some- times be found. At the extreme end of the scale we find the X-rays and the radiations of radio-active substances — if indeed these radiations are wave motions, which has been questioned. ...Lecture 3: Gravitation And The Gravitational Fleld - 1 hit(s)

... netic wave — ^that is, an alternation or periodic variation of the electromagnetic field^ — and the difference between the alternating fields of our transmission lines, the electro- magnetic waves of our radio stations, the waves of visible light and the X-rays are merely those due to the differences of frequency or wave length. The energy field at any point of space is determined by two constants, the intensity and the direction, and the force exerted by the field on a susceptible body is proportional to the ...Lecture 17: Arc Lighting - 1 hit(s)

... ainly the energetic low frequency rays. As stated, then, there is no essential differ- ence between so-called heat waves and light waves, but any radiation can be converted into other forms of energy, the so- called chemical rays of ultraviolet light, the X-ray, as well as the ultrared and the visible rays, and when converted into heat can be noticed as such. Now it just happens that most of our means of producing radiating energy give high intensi- ties of radiation only for very low frequencies, invisible ultr ...Lecture 2: Relation Of Bodies To Radiation - 1 hit(s)

... s, which are separated from each other by the blank space in the middle of the spectrum of radiation (Fig. 14). Under light waves we here include also the invisible ultra-red radiation and the ultra-violet radiation and the non-refrangible radiations, as X-rays, etc., separated from the latter by the second blank space of the radiation spectrum. In the following, mainly the light waves, that is, the second or high frequency range of radiation, will be discussed. The elec- tric waves are usually of importance on ...Lecture 4: Chemical And Physical Effects Of Radiation - 1 hit(s)

... n silver compounds, however, does not show such a response to any definite frequency, but, while strongest in the ultra-violet, ex- tends over the entire range from the frequency of green light beyond the ultra-violet and up to the highest frequencies of X-rays. That the chemical activity of radiation is some form of resonance, is, however, made very probable by the relation which exists between the active frequency range and the weight of the atom or molecule which responds to the radiation. Thus, while the fai ...Lecture 6: Luminescence - 1 hit(s)

Thus crystalline calcium tungstate, W04Ca, fluoresces white in the X-ray, light blue with ultra-violet light; the aniline dye, rhodamine, 6 G, in alcoholic solution fluoresces green in daylight, crimson in the light of the mercury lamp; willemite (calcium silicate) shows a maximum fluorescent radiation in the green, some chalc ...Chapter 6: Oscillating Currents, - 1 hit(s)

... ratio of currents is inversely proportional to the square root of the resistance of the discharge circuit, of the capacity, and of the frequency of charge. 52. Example: Assume an oscillating-current generator, feed- ing a Tesla transformer for operating X-ray tubes, or directly supplying an iron arc (that is, a condenser discharge between iron electrodes) for the production of ultraviolet light. The constants of the charging circuit are: the impressed e.m.f., e = 15,000 volts; the resistance, r = 10,000 ohms; ...Chapter 9: Inductive Discharges - 1 hit(s)
