What reading level is Researches in Physical Optics volume 1 book?
To quickly assess the difficulty of the text, read a short excerpt:
On Plate 5, Fig. 6, the last impression (the fifth) was taken after the mercury arc had been burning for half a minute, and no longer emitted the exact frequency for which the mercury molecules responded. The reflection in this case is due wholly to the quartz, and we see only the two minute points of light pre- viously referred to.
The real phenomenon is shown in Plate 5, Fig. 7, made with the clean bulb. A and B were taken at room temperature, the BY RESONATING GAS MOLECULES 71 former with a ...five-second exposure, the latter with one of half a second, to bring out better the relative intensities of the two images reflected from the inner and outer walls. I threw these out of focus a little, so that their relative intensities could be better determined. They appear expanded into circles of light due to zonal errors of the lens. It is clear that at room tempera- ture the lower circle is much brighter than the upper, which was the one reflected from the inner wall. This is doubtless due to the fact that fused quartz is not perfectly transparent to the ultra- violet, and the light which gives rise to the image reflected from the inner wall twice traverses the quartz wall which was rather thick.
