Crova's Apparatus
Crova's Apparatus, c. 1868, By Rudolph Koenig
Crova's apparatus was designed by Koenig for the purpose of "representing vibratory movements on the screen, with 8 disks." Turning the crank past a vertical slit caused the disks to rotate, while a beam of light from the optical system impinged on the slit intersections and showed the oscillatory motions. The propagation of a travelling wave, the reflection of travelling sound waves, the reflection of the movement of a continuous oscillation, the reflection of a standing wave, ether (transverse) waves, and the interference of two vibratory motions could be demonstrated by the apparatus.
