5. The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led, in the first instance, to the understanding of a concrete example of a medium which can transmit transverse vibrations and at a later stage to the definite conclusion that there is no luminiferous medium having the physical character assumed in the hypothesis 译文 为了解释光学现象,人们曾试图假定有一种具有与弹性固 体相同的物理性质的介质。这种尝试的结果,最初曾使人 们了解到一种能传输横向振动的具有上述假定所认为的那 种物理性质的发光介质。 themegallery.cwww.themegallery.com • 5.
