experimental determination of velocity of sound by air resonance method

A narrow and long hollow tube of glass or a metal, open at both ends is taken. It is partially immersed vertically in a tall jar containing water. The length of the tube above the water level in the jar serves as an air column whose natural frequency depends on its length and the diameter..

>If the prongs of a vibrating tuning fork are held on the top of a pipe, the air inside it is set into vibration by the periodic force exerted on it, by the prongs. In general, however, the vibrations are feeble, as they are forced vibrations. So, the intensity of the sound hear..

sound is given by the formula The velocity of sound in iron was determined by two French investigators by striking one end of a long series of connected iron pipes with a hammer and measuring the time interval between the two sounds heard at the..

At NTP., with pressure of air = P = 0.76 x 9.8 x 13.6 x 10 3 = 1.013 x 10 5 Pa or Nm - 2 Substituting these values in equation (1-26) But this value of the velocity of sound at 0 o C, is not in agreement with the experimental value which is 332ms -..

. The velocity of sound in hydrogen has to be four times that in oxygen. The measured values of the velocities of sound in oxygen and hydrogen are 316ms - 1 and 1284ms - 1 at NTP. This closely agrees with the predicted values. According to the kinetic theory ..

The weight w 1 of the weight hanger H is noted. A load of, say w 2 = 1kg is added to the hanger. Now, the tension in the string will be T = (w 1 + w 2 ) g newtons, where g is the acceleration due to gravity. The given tuning fork is struck on a hard rubber pad and the shank of the fork is press..

Experimental Determination of Rate of Reaction - The rate of a reaction is determined by measuring the concentration of the reactant or product at different intervals of time. The concentration is measured, by measuring a related property such as color, pressure or vol..

Speed of Sound - The flash of lightning due to collision of clouds is seen much before the thunder, although both occur simultaneously. This happens because the velocity of light is greater than the velocity of sound. The speed of sound depends on (..

Interference of sound waves can be demonstrated using Quincke's tube. It consists of two U-tubes ABCDE and FGH, whose limbs can be inserted telescopically into each other. The tube ABCDE is provided with two side tubes at B and D. The side tube at D is fitted with a rubber tube. A tuning ..
