Seite 2 - I never satisfy myself until I can make a mechanical model of a thing. If I can make a mechanical model I can understand it.
Seite 16 - Now the force or energy of the wave, which, expressed with reference to sensation, means the intensity of the light, is proportional to the square of the amplitude. Hence the amplitude being one-hundredfold, the energy of the largest light-giving waves would be ten-thousandfold that of the smallest.
Seite 160 - The results obtained are given in the following tables, in which the first line gives the incidence before and the second that after the interposition of the sugar cell.
Seite 96 - Glasses where the Circles appeared, so that all the Colours might be successively reflected from the Circles to my Eye whilst I held it immoveable, I found the Circles which the red light made to be manifestly bigger than those which were made by the blue and violet. And it was very pleasant to see them gradually swell or contract according as the Colour of the Light was changed.
Seite 93 - If the incident light is polarised at right angles to the plane of incidence, the electric vector in the light-wave has a component perpendicular to the surface on which the light falls.
