No acceptable physical explanation of this effect has been found. Because of the meteorological significance of these observations and their implication in supersonic aerodynamics, we have carried out a new determination of the velocity of sound in air at pressures down to 5 mm. mercury....

THE following simple way of arriving at the velocity of sound in air occurred to me lately :-Standing on a straight Staircase between two blank walls (brick, and papered), which I find to be 32½ inches apart, I clap my hands. The effect from each clap is a brief musical sound, ...

Recognizing that insight into the economy is a type of "organic" knowledge contributed to Keynes's emphasis on fully integrating financial conditions into the theory of income determination, influenced his arguments about invest ment behavior in the face of true uncertainty, and governed his attit ...
The velocity of sound in air at room temperature is 341 ⋅ 5 m/sec. Therefore if half a wavelength fits into the cavity at about 470 Hz, the cavity's length is 36 ⋅ 3 cm, which is almost exactly the length of a 14 inch violin. The air resonance frequencies of a 16 1 2 ...
