st that if the distance x is about a metre and a half or two metres, the term -^- #2, which enters under the radical, Kg has a large value with reference to the second term - . The ratio of these terms increases as the distance increases. Thus the law of the highest temperatures becomes more… … Kg 390. We see by the second equation that the time which corresponds to the maximum of temperature increases proportionallywith the distance. Thus the velocity of the wave (if however wemay apply this expression to the movement in question) is constant,or rather it more and more tends to become…
