Volumetric flasks are most accurate
Answer:
Wavelength of the sound wave that reaches your ear is 1.15 m
Explanation:
The speed of the wave in string is
where T= 200 N is tension in the string , =1.0 g/m is the linear mass density
Wavelength of the wave in the string is
The frequency is
The required wavelength pf the sound wave that reaches the ear is( take velocity of air v=344 m/s)
