Rubber bands. Place the resonating tube in the hydrometer jar and pour in water so as nearly to fill the jar. Strike one prong of the tuning fork on a large cork stopper and hold the vibrating fork over the open end of the tube (Fig. 54). By raising the tube slowly out of the water, a point will be found where the air-column is of just the right length to reinforce the fork. Mark with a rubber band around the tube the position of the water where the sound was loudest. Then set the fork in vibra...tion again and by raising and lowering the tube and listening intently, deter- mine again as precisely as you can the point FIG. 54 where the air-column gives the greatest reinforce- ment. Measure the length of the air-column. In a similar manner find a second position of the water surface nearer the bottom of the tube, which also gives rein- WAVE-LENGTH OF SOUND 87 forcement to the sound. Measure the length of this air- column and record the temperature of the air. The length of the short air-column (plus about 0.
