1.In Lab11, you did experiment to make the first two successive sound standing wave resonances in air column, and measured the propagation speed of sound wave (standing waves in a stopped pipe). Using the apparatus you used for Lab11, you strike a tuning fork and find that the first harmonic/fundamental resonance is produced when the air column length or height or depth at 0.166 m. If the speed of sound is 340 m/s, what is the frequency of sound wave produced by the tuning fork in Hz? Answer by giving a numerical value without the units. Keep the three-significant figures. 2.If you do the same experiment performed as in the previous question at temperature 0.0 oC, what will the frequency of the sound wave be in Hz? Answer by giving a numerical value without the units. Keep the three-significant digits
